name | type | length | unit | ucd | description |
raErr | float | 8 | deg | POS_EQ_RA_ERR | SDSS RA error |
decErr | float | 8 | deg | POS_EQ_DEC_ERR | SDSS dec error |
raDecCorr | float | 8 | CODE_MISC | SDSS ra and dec correlation | |
delta | real | 4 | arcsec | POS_ANG_DIST_GENERAL | Distance between this object and the nearest matching USNO-B object. |
match | int | 4 | CODE_MISC | Number of objects in USNO-B which matched this object within a 1 arcsec radius. If negative, then the nearest matching USNO-B object itself matched more than 1 SDSS object. | |
pmL | real | 4 | mas/year | POS_PM | Proper motion in galactic longitude. |

pmRaErr | real | 4 | mas/year | POS_PM_RA_ERR | Error in proper motion in right ascension. |
pmDecErr | real | 4 | mas/year | POS_PM_DEC_ERR | Error in proper motion in declination. |
sigRa | real | 4 | mas | CODE_MISC | RMS residual for the proper motion fit in r.a. |
