Erratum: “Stellar Halo Parameters from 4588 Subdwarfs” (ApJ, 583, 765 [2003])

Using a reduced proper motion discriminator, I obtain a sample of 4588subdwarfs from the Revised NLTT Catalog of Salim & Gould. The ample statisticsand low contamination permit much more precise determinations of haloparameters than has previously been possible. The stellar halo is not movingwith respect to the Local Standard of Rest (LSR) in either the vertical orradial direction, up to uncertainties of 2 km/s. This indicates that either theLSR is on a circular orbit or the Sun happens to lie very close to an extremumof the LSR's elliptical orbit. Similarly, tentative detections of verticalproper motion of Sgr A* relative to the LSR are either incorrect or theyreflect real physical motion of the central black hole relative to the Galacticpotential. The correlation coefficients of the halo velocity ellipsoid, whichwould reflect any possible misalignment between its principal axes and thecardinal directions of the Galaxy, vanish to within 2%. The halo subdwarfluminosity function peaks at M_V ~ 10.5 with a full width half maximum of about2.5 mag.Comment: Submitted to ApJ, 22 pages including 2 figure
