Thanks Markus,

I'm not sure why I didn't plot this myself, it does look like the curves
overlap a bunch. I found the information on the companies website
https://support.planet.com/hc/en-us/articles/360000552387-Do-you-provide-PlanetScope-Relative-Spectral-Response-RSR-curves-

I have downloaded the file - it contains 3 satellite families.
Splitting up into 3 CSV files, the curves look ok (files attached).

You may try again with these files (probably all should be added to
i.atcorr, separately).

Dear Markus and Gwen(all?),

Iam new to grass gis and want to run the atcorr over Planet scene.
Can you please give me a hint how to enter those values into the parameter
file (see below)?

Lets say Iam going to run the atcorr over the blue band using the *.csv you
posted. Here is a partial parameter file:

13 - geometrical conditions=Rapideye ETM+ (using
rapideye parameter instead)
5 12 09.40 47.455 8.250 - month day hh.ddd longitude latitude ("hh.ddd" is
in decimal hours GMT)
2 - atmospheric mode=midlatitude summer
1 - aerosols model=continental
15 - visibility [km] (aerosol model concentration)
-0.600 - mean target elevation above sea level [km]
(here 600m asl)
-1000 - sensor height (here, sensor on board a
satellite)
??? - Sensor band

Best,
Rob
