 nice.

 Sorry, we should have reported the command we used. If I run exactly your
 case:

 {{{
 i.atcorr -r input=B08 elevation=dem range=0,10000 output=test_atcorr
 rescale=0,10000 parameters=p6s.txt
 }}}

 I get the same output as you:

 {{{
 r.info -r test_atcorr
 min=8.708314e-10
 max=10000
 }}}

 So, it seems to be essential to use both range and rescale option if one
 wants the data to be exactly in a given range of values...
 Maybe something to clarify in the manual or set as a parser rule / warning
 in the module?
