Object batches

Object batches are generated from the IPP for objects that have set for the year and that have been fully processed by the IPP. Data is taken entirely from DVO FITS files, specifically:

• cpt file: contains ..., definition here​
• cps file: contains mean mags etc definition here​

One PSPS batch represents one DVO 'region', eg these files

s3000/7471.10.cps
s3000/7471.10.cpt

would be used to create an object batch for this DVO region.
