Astrometric Columns

There are columns for the Right Ascension and declination, position error, corrected Right Ascension and Declination, galactic longitude and galactic latitude. The corrected (RA_CORR and DEC_CORR) columns refer to the Right Ascensions and declinations with the astrometric correction applied (if correction successful, POSCOROK = TRUE). If the correction wasn't successful (POSCOROK = FALSE) then these coordinates will be the same as the uncorrected ones.
