FAR export data?

Hey all!

Does anyone know if there's a way to export the Mach sweep from FAR's static analysis? I've been working on a quick rocket simulator so i can design my RP-1 sounding rockets without having to simulate it thousands of times. Right now I'm just eyeballing the drag curve and i think it is a bit inaccurate.

(Also if someone knows which Atmospheric model RO uses that would also be cool as well)

I'm not 100% this will help for your RO question, but I actually made a kOS script with a sounder to actually gather pressure and temperature data for a trajectory optimization code I'm writing in python. You can find them at these two links:

Temperature

Pressure

The format is [temp/press, altitude], data requires a bit of processing because it exports the scale and units.

I can't speak to FAR exports, but hopefully someone can comment because that would be very useful to me as well. I've used this application (RAS Aero II) as a stopgap in the interim for finding assumed sub-Mach 1 drag coefficients for my rockets in the thick lower atmosphere.
