 Dear grass gis team,
 actually I am working with several RapidEye (product Type L3A)
 acquisitions, in order to pre-process them for classification. It occurred
 to me that in some cases i.atcorr creates a results for the first band
 (blue), which seems to be “biased”. I applied i.atcorr on different
 machines and used different versions of Grass, but the issue is

 Grass versions I tried on a Windows7 Professional, 64-bit system:
 6.4.4, 7.0.0beta4 and 7.1svn

 Input text file values I used:


 5 25 12.8 52.09413 -10.22328








 For the input imagery and its range a used the min and max values of the
 radiance image. As input altitude raster map a 5m DEM was used and for
 rescale output the range 0,1.

 Please let me know if you need further information!
 Many thanks in advance!!
