Script needed: Read housekeeping with frames running #11
Description
Activity
It would be possible to extend the ObsSim software to support a mode (hk_only) where frames are running, housekeeping is transmitted, but the pixel data udp packets are not. This would make the data rate low enough to easily receive/process hk from python. The risk of adding this is, of course, that the feature may be activated by accident and a user will be expecting pixels but only see hk.
This script should obtain a full set of housekeeping data and output them in a standard format, in engineering units. This script is intended to capture HK data with frames running. The output values should be compared to a reference set.
Note: This script will be used for Functional testing of the FPE stack, thus it will be run in situations where the Interface, Driver, and Video boards are mated together.
This script can either retrieve HK data from the frames (FITS files) as they arrive from the ObsSim, or in some more direct fashion, if the Python package supports it.
NOTE however, that the main goal of tests running this script will be to evaluate whether HK data is being affected by the action of the frames running, as compared with obtaining the same data without frames running. Thus, whichever method is used, it must accurately reflect the housekeeping data the science operations team will receive when TESS is operational.
