[GRASS-user] i.atcorr for GeoEye-1 and Worldview-3

[Kamhul Camhol]

Dear Moritz,

Yes, for GeoEye-1 and Worldview-3, the: A) geometric conditions and F) band values, two of the required inputs/parameters for the GRASS i.atcorr 6S  algorithm. 

Thank you. Sincerely,
Armand

Do I understand correctly that you would need the numbers behind the 
curves in this document:
