Provide RA/Dec of exposure

[pmelchior]

Don't need WCS positions, but, say, center-chip location would be nice to have.
It would suffice to have that coordinate in the FITS header.

Do the new y1p1 data have the RA/Dec in the header?

[esheldon]

yes, but I'm not sure how accurate they are

This one looks wrong
RA = '00:00:00.000' / [HH:MM:SS] Target RA
DEC = '00:00:00.000' / [DD:MM:SS] Target DEC
TELRA = '00:00:00.068' / [HH:MM:SS] Telescope RA
TELDEC = '00:00:00.101' / [DD:MM:SS] Telescope DEC

This one looks OK
RA = '23:07:30.365' / [HH:MM:SS] Target RA
DEC = '00:04:24.326' / [DD:MM:SS] Target DEC
TELRA = '23:07:30.407' / [HH:MM:SS] Telescope RA
TELDEC = '00:04:24.398' / [DD:MM:SS] Telescope DEC
HA = '01:48:03.360' / [HH:MM:SS] Telescope hour angle

(well maybe not wrong if it really was targeted at 0,0

I like the second better. The first is suspiciously close to zero...

Anyway, so I can pull them from the header now. Needs: a place to put them in the viewer.

Along the same lines, it might be useful to have the date the exposure was taken. I think DATE-OBS is the header keyword that you want:
DATE-OBS= '2013-09-01T05:32:05.089479' / UTC epoch
or possibly for the calendar date:
DTCALDAT= '2013-08-31 ' / calendar date from observing schedule
