Coordinate System #114

Closed panagiotispir closed 5 years ago

panagiotispir commented 5 years ago

Not an Issue but just a question. I would like to inform what exactly coordinate system is pyglow using? I saw a coord.py file which includes some functions about coordinates, but I can't underastant which system exactly pyglow using. Sorry for issue creation, I didn't find another way to contact with you. thanks in advance

x = East y = North z = Up

I guess you'd call this local geographic. The fact that this is not obvious is because we don't have a good API (which is issue #24 )

Sorry about reopening this issue. According to fortan code of models, all of them have the ability to run on different coordinate systems such as GEO(geographic) or GEOD(geodetic) or MAG(geomagnetic). I tried to read pyglow code to understand where pyglow does this selection, but I couldn't find it. Because your answer wasn't 100% clear for me, I would like to ask you again. When I create the point for pyglow, am I using GEO coordinates for all models(IRI,HWM, MSISE,IGRF) that pyglow use?
