Dear friends,
Where may I read about an atmospheric correction method called DOS 2b? I found the information of all the modifications excludind Dos 2b...
I cannot find latter in Grass manuals

Thank you in advance.

In the source code [1]:

DOS2b includes an estimation for TAUv = cos(constant)

where the constant depends on the satellite (9.2 for Landsat<4, 8.2 for the others). No idea where that constant comes from.

This should be better documented in the man page.
