Hi Micha,
did you refer to the input range?
Yes, the input range.
I did so and checked bands 1-9 with r.info -r. Top of atmosphere
reflectance values are all in the range of -0.01 - 2.12. The
negative value seems to be a outlier and I check in addition
with the range 0-2.12.
I used these values for the input range in i.atcorr -r and used
0,1 as output range.
I meant in the first i.landsat.toar step. The input (DN) values
should be up to 700 or so. Landsat 8, with its 12 bit data can have
max DN values of 4096. But I didn't use that full range, rather the
actual DN range of the original images.
However I get even smaller reflectance values (0.15 respectively
0.29 for vegetation in band5)
