A few issues I have been involved with over the last few months:

Vignetting correction

WCS enabled headers

Extinction correction

Mosaicing blocks

Copying part of a FITS file

Fully mosaiced plates

SBUP: Sliding Box for Uniform Photometry

First shot at zero points of plates

Plate EPOCHs (original) and RA DEC for their centers (nominal)
Plate RA DEC for their centers i.e. pixel (11520,11520)
Plate extremes:
This set of plates (2045) have proper extremes
This set of plates (73) have something that needs correcting
This set of plates (564) do not have online catalogs and hence limits unavilable (or plates unavailable)
