 This depends on your input data and your range parameter:

 {{{
 r.info -r B08
 min=83
 max=7110

 i.atcorr -r input=B08 elevation=dem range=83,7110 output=test_atcorr
 rescale=0,10000 parameters=BROL/STEFAN/p6s.txt --v --o

 r.info -r test_atcorr
 min=8.732422e-10
 max=10000
 }}}

 i.e. if you tell it to scale the input data range to 0,10000 it will do
 so, but if you tell it that the input range is 1,10000 then it will scale
 this range to 0,10000.

 Markus, could it be that you are using the original larger input image
 from the ML and not the smaller clip attached to this ticket ?
