Can anyone walk me through understanding the output .csv file.
I apologize in advance for the silly question, but what exactly am I looking at? How would I go about converting that output to something like the calibration data found on http://nova.astrometry.net
Thank you in advance for the help

The output csv is the unit test output, and contains the list of star IDs. -1 means that the object was not identified, otherwise it’s the hiparcos ID of the star. 

For an astrometry.net like output you probably want to be looking at startracker.py, which can give you either a 3x3 matrix that converts body frame to inertial. Alternately you can get star ids or star vectors in the body and inertial frame
