IMWCS DSS: Telescope Image Header With WCS

Before fit: [Image/GSC] [Map/GSC] [Image/DSS] [Map/DSS] [Header]
[Stars]__ After fit: [Image/GSC] [Map/GSC] [Image/DSS] [Map/DSS] [Header]

This image header has a world coordinate system fit using sources from the Digitized Sky Survey. The original RA, DEC, and EQUINOX keywords are renamed WRA, WDEC, and WEQUINOX, and a new center, equinox, and FITS WCS keywords are added at the end of the file, as well as an IMWCS character string giving the version of the program which was used to fit the WCS.
