For targets identified with, for eaxmple, ds9 code like usno_identify, we can combine information from both the MIDO data in the image *.info file and the catlog data in the CDFP (CoorDinate Floating Point) file. The most obvious application, and the reason I wrote this, is to provide a was of builing a table of centroided X,Y data and the corresponding Ra,Dec positions. However, you could do other useful things like make a matched set of magnitues like MagZP30 (a magnitude for a CCD image computed with MIDO) and Bmag (the USNO Blue magnitude). Before jumping into coding this up, i I surveyed existing codes and made some useful notes with examples.
