TABLE ProperMotions

Proper motions combining SDSS and recalibrated USNO-B astrometry.

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.

pmB real 4 mas/year POS_PM Proper motion in galactic latitude.

pmRa real 4 mas/year POS_PM_RA Proper motion in right ascension.

pmDec real 4 mas/year POS_PM_DEC Proper motion in declination.

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.

sigDec real 4 mas CODE_MISC RMS residual for the proper motion fit in dec.

nFit int 4 CODE_MISC Number of detections used in the fit including the SDSS detection (thus, the number of plates the object was detected on in USNO-B plus one).

O real 4 mag PHOT_MAG_G Recalibrated USNO-B O magnitude, recalibrated to SDSS g

E real 4 mag PHOT_MAG_R Recalibrated USNO-B E magnitude, recalibrated to SDSS r

J real 4 mag PHOT_MAG_G Recalibrated USNO-B J magnitude, recalibrated to SDSS g

F real 4 mag PHOT_MAG_R Recalibrated USNO-B F magnitude, recalibrated to SDSS r

N real 4 mag PHOT_MAG_I Recalibrated USNO-B N magnitude, recalibrated to SDSS i

dist20 real 4 arcsec POS_ANG_DIST Distance to the nearest neighbor with g < 20

dist22 real 4 arcsec POS_ANG_DIST Distance to the nearest neighbor with g < 22
