   Hier die gesammelten Kalibrationskoeffizienten für AT_KSO_1

   X = c ( b (a exp (n(1+dT)/a) - 1) + n ) 

   n ... counts (sensor output)
   X ... physical quantity (total radiation in [W/m²] 
         or horizontal illumination [Lux]) 

   a = 1.1282e+05, b = 1.0924e-03, c = 5.7836e-09, d = 3.9002e-03  [W/m²]
   a = 1.1282e+05  b = 1.0924e-03  c = 5.1146e-07  d = 3.9002e-03  [Lux]
  
  Background X0= 0.444 mlx

  Conversion factors determined from total radiation model and independent
  total radiation measurments.
