I was wondering if you knew at all how latitude is input (eg. is the equator 0 degrees or 90). When I ran it, I input -90 for my value of latitude and 0.5 GeV for geomagnetic cutoff acceptance, and as far as I can tell it did not create any extra files. are these parameters acceptable?
In principle those parameters could be used. When using the atmloc.f, by selecting “Geographic coordinates” you can provide latitude/longitude in degrees. The routine will create atmloc.geo, atmlocmat.cards, atmloc.sur which you can include in the inp via the GEOBEGIN (for the .geo) and #include cards.
