                          Description of Data in the WDS                       
 +
                                                                               
 +
Columns  1- 10:    The  hours, minutes, and tenths of minutes of Right
 +
                    Ascension for 2000, followed by the degrees and minutes of
 +
                    Declination for 2000, with + and - indicating north and
 +
                    south declinations. The positions given represent our best
 +
                    estimates of these values. Where possible, these are based
 +
                    on the ACRS and PPM data, with proper motion incorporated.
 +
                                                                               
 +
Columns  11- 17:    The discoverer, identified by his one-to-three letter code,
 +
                    and his discoverer's number, if assigned. The reference list
 +
                    should be consulted first to identify individuals. However,
 +
                    some discoverer designations do not appear in this list, for
 +
                    various reasons, and a supplementary list is provided.
 +
                                                                               
 +
Columns  18- 22:    Components, when the object has more than two. The Lick IDS
 +
                    scheme has been discontinued, and components are now
 +
                    referred to by the traditionally employed lower-case
 +
                    letters. The rather awkward upper-case designations, e.g.
 +
                    ABXC, have been changed to the form AB-C, etc. We have noted
 +
                    some confusion on the part of observers and students alike,
 +
                    as to how to designate components in multiple systems.
 +
                    Traditionally, these have been designated in order of
 +
                    separation, thus AB, AC,...., or in the cases where close
 +
                    pairs are observed blended, AB-C, AB-D,.... In some
 +
                    instances, differing resolution limits produce situations
 +
                    where observations are intermixed, thus AC, AB-C, and so
 +
                    forth (in all too many cases, carelessness on the part of
 +
                    the observer does not permit us to determine with certainty
 +
                    how the observation is to be interpreted). There are also
 +
                    many instances where later observations have revealed a
 +
                    closer companion; these are designated Aa, Bb, etc. In a few
 +
                    cases wider, later discoveries have also been so denoted.
 +
       
 +
Columns  24- 27:    The dates of the first and last observations of an object
 +
        29- 32:    (of satisfactory accuracy), up to the present date.
 +
                                                                             
 +
Columns  34- 37:    The number of measures of the object.
 +
                                                                               
 +
Columns  39- 41:    Position angles in degrees for the dates listed in columns
 +
        43- 45:    26-34. Crude positions (e.g., NP) of the past have been
 +
                    changed to their degree equivalent with an accompanying note
 +
                    in the data line of the measurement database. Position
 +
                    angles are unprecessed in this catalog (i.e., they are for
 +
                    the mean date of observation).                     
 +
                                                                               
 +
Columns  47- 51:    The distances in seconds of arc, and tenths, for the dates
 +
        53- 57:    listed in columns 26-34. Some separations are treated by the
 +
                    codes found in columns 100-101, or in the Notes.
 +
                                                                               
 +
Columns  59- 63:    Magnitudes of the two components. See the Introduction for
 +
        65- 69:    discussion.
 +
                                                                               
 +
Columns  71- 79:    Spectral type of A, or of two components, if space permits.
 +
                    See the Introduction for discussion.
 +
                                                                             
 +
Columns  81- 84:    The components of the proper motion in seconds of arc per
 +
        85- 88:    1000 years, in right ascension reduced to great circle, and
 +
                    in declination. Specifically, this catalog lists 15mu(alpha)
 +
                    cos(delta), where mu(alpha) is in seconds of time, and   
 +
                    mu(delta) is in seconds of arc. Both quantities are reduced
 +
                    to a time unit of 1000 years. The exceptions are those
 +
                    objects coded P for which an explanation is given under the
 +
                    description for Columns 108 to 111. + and - indicate
 +
                    eastward and westward motions in Right Ascension, and + and
 +
                    - those north and south in Declination. Where possible, this
 +
                    comes from Tycho-2.
 +
 +
Columns  90- 93:    Proper motion of the secondary, when known.
 +
        94- 97:   
 +
 +
                                                                             
 +
Columns  99-106:    Durchmusterung number of the object in the system used by
 +
                    the Henry Draper Catalogue: Bonn from +89 degrees to -22
 +
                    degrees inclusive, Cordoba from -23 degrees to -51 degrees
 +
                    inclusive, Cape Photographic from -52 degrees to -89
 +
                    degrees inclusive. When a star is not contained in the
 +
                    Durchmusterung proper to its declination zone, but is
 +
                    contained in another Durchmusterung, this is so indicated
 +
                    in the Notes. Other components having different
 +
                    Durchmusterung numbers are also indicated in the Notes.
 +
                                                                               
 +
Columns 108-111:    The following codes are contained in these columns:
 +
 +
                        N: Notes found in the Notes table.                   
 +
                        B: Summary line gives blue (Johnson U or B, blue
 +
                          photographic, etc.) magnitudes
 +
                        C: Orbit and Linear solution. A published orbit exists
 +
                          and this system has a Linear Solution as well. A "C"
 +
                          code, then, indicates both an "O" and an "L" code.
 +
                        I: Identification uncertain. Match of object at precise
 +
                          position with WDS pair may or may not be correct.
 +
                          Currently under examination.
 +
                        K: Summary line gives K-band or other infrared (>1
 +
                          micron) magnitudes       
 +
                        L: Linear solution. Linear elements for this pair have
 +
                          been determined. Linear Elements Catalog is
 +
                          currently under devlopement.
 +
                        M: Magnitude modified. Magnitudes have been corrected
 +
                          to the Tycho-V scale based on other systems measured
 +
                          by the discoverer and Tycho.
 +
                        N: Notes found in WDSNOT MEMO of WDS
 +
                        O: Orbit, briefly described in WDSNOT MEMO and has
 +
                          entry in Orbit Catalog
 +
                        P: 100-year proper motion in right ascension and
 +
                          declination
 +
                        R: Summary line gives red (Johnson R or I, red
 +
                          photographic, etc.) magnitudes               
 +
                        S: Statistically different parallax and proper motion
 +
                          indicates that this pair is non-physical.
 +
                        T: Statistically the same parallax within the errors and
 +
                          similar proper motion or other technique indicates
 +
                          that this pair is physical.
 +
                        U: Proper motion or other technique indicates that this
 +
                          pair is non-physical.
 +
                        V: Proper motion or other technique indicates that this
 +
                          pair is physical.
 +
                        W: System has additional components and/or measures in
 +
                          the WDS Supplement (WDSS) catalog.
 +
                        X: A "Dubious Double" (or "Bogus Binary"). This pair may
 +
                          represent a positional typo in the original publication
 +
                          (so we're looking in the wrong location), an optical
 +
                          double disappearing due to radically different proper
 +
                          motions, a plate flaw, or simply a pair not at a
 +
                          magnitude, separation, etc., sufficiently similar to
 +
                          those noted when the first measure was added (making
 +
                          it too faint, too close, etc.). We would certainly like
 +
                          to know about any circumstances where you have found or
 +
                          have ascertained the mystery behind these pairs.
 +
                        Y: Statistically different parallax for the components
 +
                          indicates they are non-physical.
 +
                        Z: Statistically the same parallax within the errors would
 +
                          indicate the components are physical.
 +
 +
                    At present, column 108 is reserved for N, column 109 for
 +
                    O, L, C, or X and column 110 for W. The other codes can
 +
                    occur in any column.
 +
                                                                             
 +
Columns 113-130:    The hours, minutes, seconds and tenths of seconds (when

                    known) of Right Ascension for 2000, followed by the degrees,

                         Description of Data in the WDS

Columns 1- 10: The hours, minutes, and tenths of minutes of Right 

                   Ascension for 2000, followed by the degrees and minutes of
                   Declination for 2000, with + and - indicating north and
                   south declinations. The positions given represent our best
                   estimates of these values. Where possible, these are based
                   on the ACRS and PPM data, with proper motion incorporated.

Columns 11- 17: The discoverer, identified by his one-to-three letter code, 

                   and his discoverer's number, if assigned. The reference list
                   should be consulted first to identify individuals. However, 
                   some discoverer designations do not appear in this list, for
                   various reasons, and a supplementary list is provided.

Columns 18- 22: Components, when the object has more than two. The Lick IDS 

                   scheme has been discontinued, and components are now
                   referred to by the traditionally employed lower-case 
                   letters. The rather awkward upper-case designations, e.g. 
                   ABXC, have been changed to the form AB-C, etc. We have noted
                   some confusion on the part of observers and students alike,
                   as to how to designate components in multiple systems. 
                   Traditionally, these have been designated in order of 
                   separation, thus AB, AC,...., or in the cases where close 
                   pairs are observed blended, AB-C, AB-D,.... In some 
                   instances, differing resolution limits produce situations
                   where observations are intermixed, thus AC, AB-C, and so
                   forth (in all too many cases, carelessness on the part of
                   the observer does not permit us to determine with certainty
                   how the observation is to be interpreted). There are also
                   many instances where later observations have revealed a
                   closer companion; these are designated Aa, Bb, etc. In a few
                   cases wider, later discoveries have also been so denoted.

Columns 24- 27: The dates of the first and last observations of an object 

        29- 32:    (of satisfactory accuracy), up to the present date.

Columns 34- 37: The number of measures of the object.

Columns 39- 41: Position angles in degrees for the dates listed in columns 

        43- 45:    26-34. Crude positions (e.g., NP) of the past have been
                   changed to their degree equivalent with an accompanying note
                   in the data line of the measurement database. Position 
                   angles are unprecessed in this catalog (i.e., they are for 
                   the mean date of observation).

Columns 47- 51: The distances in seconds of arc, and tenths, for the dates 

        53- 57:    listed in columns 26-34. Some separations are treated by the
                   codes found in columns 100-101, or in the Notes.

Columns 59- 63: Magnitudes of the two components. See the Introduction for 

        65- 69:    discussion.

Columns 71- 79: Spectral type of A, or of two components, if space permits. 

                   See the Introduction for discussion.

Columns 81- 84: The components of the proper motion in seconds of arc per 

        85- 88:    1000 years, in right ascension reduced to great circle, and
                   in declination. Specifically, this catalog lists 15mu(alpha)
                   cos(delta), where mu(alpha) is in seconds of time, and     
                   mu(delta) is in seconds of arc. Both quantities are reduced
                   to a time unit of 1000 years. The exceptions are those 
                   objects coded P for which an explanation is given under the
                   description for Columns 108 to 111. + and - indicate 
                   eastward and westward motions in Right Ascension, and + and
                   - those north and south in Declination. Where possible, this 
                   comes from Tycho-2.

Columns 90- 93: Proper motion of the secondary, when known. 

        94- 97:


Columns 99-106: Durchmusterung number of the object in the system used by 

                   the Henry Draper Catalogue: Bonn from +89 degrees to -22
                   degrees inclusive, Cordoba from -23 degrees to -51 degrees
                   inclusive, Cape Photographic from -52 degrees to -89 
                   degrees inclusive. When a star is not contained in the 
                   Durchmusterung proper to its declination zone, but is 
                   contained in another Durchmusterung, this is so indicated 
                   in the Notes. Other components having different 
                   Durchmusterung numbers are also indicated in the Notes.

Columns 108-111: The following codes are contained in these columns: 

                       N: Notes found in the Notes table.                     
                       B: Summary line gives blue (Johnson U or B, blue
                          photographic, etc.) magnitudes
                       C: Orbit and Linear solution. A published orbit exists
                          and this system has a Linear Solution as well. A "C"
                          code, then, indicates both an "O" and an "L" code.
                       I: Identification uncertain. Match of object at precise
                          position with WDS pair may or may not be correct.
                          Currently under examination.
                       K: Summary line gives K-band or other infrared (>1
                          micron) magnitudes         
                       L: Linear solution. Linear elements for this pair have
                          been determined. Linear Elements Catalog is
                          currently under devlopement.
                       M: Magnitude modified. Magnitudes have been corrected
                          to the Tycho-V scale based on other systems measured
                          by the discoverer and Tycho.
                       N: Notes found in WDSNOT MEMO of WDS
                       O: Orbit, briefly described in WDSNOT MEMO and has
                          entry in Orbit Catalog
                       P: 100-year proper motion in right ascension and
                          declination
                       R: Summary line gives red (Johnson R or I, red
                          photographic, etc.) magnitudes                
                       S: Statistically different parallax and proper motion
                          indicates that this pair is non-physical.
                       T: Statistically the same parallax within the errors and
                          similar proper motion or other technique indicates
                          that this pair is physical.
                       U: Proper motion or other technique indicates that this
                          pair is non-physical.
                       V: Proper motion or other technique indicates that this
                          pair is physical.
                       W: System has additional components and/or measures in
                          the WDS Supplement (WDSS) catalog.
                       X: A "Dubious Double" (or "Bogus Binary"). This pair may
                          represent a positional typo in the original publication
                          (so we're looking in the wrong location), an optical
                          double disappearing due to radically different proper
                          motions, a plate flaw, or simply a pair not at a
                          magnitude, separation, etc., sufficiently similar to 
                          those noted when the first measure was added (making
                          it too faint, too close, etc.). We would certainly like 
                          to know about any circumstances where you have found or
                          have ascertained the mystery behind these pairs.
                       Y: Statistically different parallax for the components
                          indicates they are non-physical.
                       Z: Statistically the same parallax within the errors would
                          indicate the components are physical.

                   At present, column 108 is reserved for N, column 109 for
                   O, L, C, or X and column 110 for W. The other codes can 
                   occur in any column.

Columns 113-130: The hours, minutes, seconds and tenths of seconds (when 

                   known) of Right Ascension for 2000, followed by the degrees,
                   minutes, and seconds of Declination for 2000, with + and - 
                   indicating north and south declinations. The positions given
                   represent our best estimates of these values. Where 
                   possible, these are based on the Hipparcos and Tycho data, 
                   with proper motion incorporated. While the arcminute 
                   coordinate (columns 1-10) refer to the primary of a multiple
                   system, the arcsecond coordinate (columns 113-130) refer to
                   the primary of the subsystem. For example, while the BC pair
                   of an A-BC multiple will have the same 10 digit WDS 
                   coordinate, the arcsecond coordinate of the BC pair will be
                   at the "B" position.
