Dear Grass developers, In a previous message I mentioned that the i.atcorr module returns nan values for Landsat 5 TM bands 1 and 2. Today I was processing some RapidEye images and found out that i.atcorr fails to process bands 4 and 5. Notice that when I processed this bands as if they were band 1, i.atcorr returned the expected result. This means that there is nothing wrong with the image files.
I hope that the Fortran source code that I shared with you has the answers to solve this issue.
