Here's an explanation of the ident files

1   - fuv only identified 
2   - ident number in xg-gsp.fits file
3   - GALEX name
4,5 - GALEX position, RA & DEC
6   - distance from center of galaxy, in arcmins
7   - distance from center of galaxy, in kpc, assuming heliocentric
      velocity of galaxy is part of Hubble flow [change to
      galactocentric?]
8   - redshift of object. -1 if not known. Given as '0' if identified
      as star. Objects measured spectroscopically as star have real
      zeros (with decimal point)
9   - Simply classification: f-from selected foreground galaxy itself;
      q-qso; s-star; u-unclassified 
10  - Measured (mean) FUV flux between 1450 and 1750A, units of e-15
11  - FUV mag, from xg-gsp.fits data
12  - comments, other IDs, etc
