- Form: RPREP
RPREP reads a record from a batch surface photometry preparation file
opened using OPREP. These files contain the following information (one
record per image):
- SKY value (into VISTA variable SKY)
- max. radius for photometry (into variable RMAX)
- estimated HWHM for the PSF (into variable PSF)
- contents of the AXES block (into AXES)
- image header (ignored by this routine).
This information must already have been written into the prep-file using
the WPREP. OPREP opens the file, which must have already been opened
read-only using the `OPREP R' command
