Revision of Radial Velocities
-----------------------------

Radial velocities of improved accuracy have been reported for a number of stars in our revised catalog based on high-resolution spectroscopic follow-up, in particular for the HK survey stars (McWilliam et al. 1995; Norris, Ryan, & Beers 1996). The adopted radial velocities are reported in column (7) of Table 1A. Errors on the radial velocity measurements are reported in column (8), and the source of the radial velocity estimate is provided in column (9). For the HK survey stars with only medium-resolution spectroscopy available, we adopt a conservative error estimate of 10  (based on previous comparisons). For non-variable stars where the original authors did not report an error on the velocity determination, we have adopted an error of 10 . For RR Lyrae variables without reported radial velocity errors, we assign an error of 30 , which accounts for the uncertainty in the systemic velocity arising from limited phase coverage in spectra for a given variable (Smith 1995).
