Abstract:
The machine-readable version of Radial Velocities of High-Proper-Motion
Stars contains UBV photometry, proper motions, and radial
(line-of-sight) velocities for 878 high-proper-motion stars that were
selected from the subdwarf candidate list of Sandage and Fouts (1986).
Introduction:
The title and source document refer to data for 889 high-proper-motion
stars taken from the list of subdwarf candidates compiled by Sandage and
Kowal (1986). However, eleven stars found to have variable velocities
are omitted from both the published table and the machine-readable file.
The primary data are new radial velocities determined from 2265
measurements made from observations with the Mount Wilson 2.5-meter
telescope coude spectrograph with a Reticon detector. The
internal error of a single measurement was determined to be 1 sigma. =
4.7 km/s, while 88 stars in common with previously known subdwarfs gave
an external error of 1 sigma. = 6.9 km/s per measure. The velocity
system was determined to be on the system of the Wilson General
Catalogue of Stellar Radial Velocities (Wilson 1953) to better than 1
km/s. There are 38 stars in the catalog having line-of-sight velocities
larger than v(r) = 200 km/s, of which 22 are new.
The source reference should be consulted for additional information
concerning sample selection, instrumentation and spectral coverage,
reduction procedures, and results of the data analysis.

Note on flag:
An asterisk (*) flag to indicate stars for which prior radial-velocity
data were reported in Sandage (1969), Sandage (1981), Wilson (1953), and
Eggen (1964).
Note on id:
Star designation. Lowell Observatory designations (Giclas, Burnham, and
Thomas 1971) are given if they exist. Otherwise, designations from the
Luyten proper-motion catalogs (Luyten 1979, 1980; Luyten and Hughes
1980), the Durchmusterungen (Bonner Durchmusterung, Argelander 1859-62,
Kuestner 1903, Schoenfeld 1886; Cordoba Durchmusterung, Thome 1892-1932;
Cape Photographic Durchmusterung Gill and Kapteyn 1895-1900), or the
Selected Area catalogs are given.
Note on V, B-V, and U-B:
UBV data taken from Sandage and Kowal (1986).
Note on pmRA and pmDE:
The adopted proper motions have been averaged from the Lowell and Luyten
catalogs, the latter proper motions in r and theta being converted to
proper motions in right ascension and declination via the following
relations:
pmRA = pm(r)*sin(theta)
pm(Dec)= pm(r)*cos(theta)
Note on pm_lon and pm_lat:
The galactic proper motions, pm_lon and pm_lat, are calculated from the
equatorial motions and the parallactic angle (phi):
pm_lon = pmRA*cos(phi) + pmDE*sin(phi)
pm_lat = -pmRA*sin(phi) + pm_DE*cos(phi)
Note on phi:
The angle between the equatorial and galactic coordinate systems (see
Smart 1968, pp. 17-19).
History:
The machine-readable data file of New Subdwarfs. V. Radial
Velocities for 889 High-Proper-Motion Stars Measured with the Mount
Wilson 100-inch Reflector was received from Dr. K. U. Ratnatunga of
the Space Data and Computing Division, NASA/Goddard Space Flight
Center, on 8 April 1989. Permission to archive and distribute the
data was subsequently obtained at different times during
conversations with the authors. Minor format modifications were
made to the catalog at the Astronomical Data Center in order to add
plus signs to certain data, to position all signs to occur always
in the same bytes, and to remove multiple spaces from between the
data columns to decrease storage requirements. (A single space has
been retained between each data field to facilitate reading the
data.)
Acknowledgments:
Appreciation is expressed to K. U. Ratnatunga for supplying the data
file and to G. Fouts and A. Sandage for extending permission to archive
and distribute the catalog from the data centers. The authors also
kindly reviewed a draft version of this document prior to its release
for distribution with the machine-readable catalog.
