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 1σ=4.7km/s,
while 88 stars in common with previously known subdwarfs gave an
external error of 1σ=6.9km/s per measure. The velocity system
was determined to be on the system of the Wilson General Catalogue of
Stellar Radial Velocities (Wilson 1953, Cat. III/21) to better than
1km/s. There are 38 stars in the catalog having line-of-sight
velocities larger than v(r)=200km/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 (1969ApJ...158.1115S 1969ApJ...158.1115S), Sandage
(1981AJ.....86.1643S 1981AJ.....86.1643S), Wilson (1953, Cat. III/21), and Eggen
(1964RGOB...84..111E 1964RGOB...84..111E, "A catalogue of high-velocity stars").
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 and Hughes 1980, NLTT and
supplement, Cat. I/98) the Durchmusterungen (Bonner Durchmusterung,
Argelander 1859-62, Kuestner 1903, Schoenfeld 1886, Cat. I/119 and
I/122; Cordoba Durchmusterung, Thome 1892-1932, Cat. I/114; Cape
Photographic Durchmusterung Gill and Kapteyn 1895-1900, Cat. I/108),
or the Selected Area catalogs are given.
Note on Vmag, 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)
pmDE = pm(r)*cos(theta)
Note on pmGlon and pmGlat:
The galactic proper motions, pmGlon and pmGlat, are calculated from
the equatorial motions and the parallactic angle (phi):
pmGlon = pmRA*cos(phi) + pmDE*sin(phi)
pmGlat = -pmRA*sin(phi) + pm_DE*cos(phi)
Note on phi:
The angle between the equatorial and galactic coordinate systems
(see Smart 1968, "Stellar Kinematics", Cambridge University Press,
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.
