Implementing automated corrections for beamforming flux #13

Use beamforming calibration tables to determine beamforming flux correction factors.
Determine time-dependent correction factors by considering 1) the exact factor csv file to be used and 2) solar altitude
Apply the correction factors to the beamforming data and generate new hdf5/fits files. These would be our level 1 data products.
Determine background from daily drift scan data and subtract it from the data, export hdf5/fits files. These would be our level 1.5 data products.

@peijin94 I believe that you have already implemented the automated corrections, right? If yes, can you please update this issue, with the relevant pull requests, as needed?

Yes, in the creation of the beamform daily preview.

The current reduced spectrum in pipeline are calibrated to the best knowledge we have except for primary beam correction. I have a note about this https://peijinz.notion.site/OVRO-LWA-spectrum-reduced-DB-f74ff09f4479437ba2a15283723613e6?pvs=4
