A SEARCH FOR FAINT BLUE STARS

Ever since the inception of my seaches for Faint Blue Stars I have tried to
determine proper motions for as many of them as possible - for the simple
reason that this is the most direct and reliable way to obtain information
on the distribution of their luminosities. Thus, proper motions have been
published in numerous issues of these publications. Now that my work on
Faint Blue Stars has come to an end virtually and at the same time, the
picture of the luminosities is beginning to clarify, it would seem worth
while to gather all the information on the proper motions of these objects
into a single publication.
Herewith are given, therefore, all proper motions I have derived for these
faint blue stars; most of these motions were originally published in scattered
issues of these same publications.
The Table which follows gives data for 951 stars, the first column showing
the designation of the object, usually its HZ, LB, or PHL number, though I
have used B.D. designations wherever possible and have retained the variable
star designations for the SS Cygni variables and Novae measured in XXXVI. The
next four columns give the position for 1950, the estimated photographic
magnitude and the color. This last quatity is sometimes expressed by giving
the spectral class but more often either by the color index estimated by my
usual differential method, or by the two-color estimates Haro and I have given
in the PHL catalogue. The next four colums give the components of proper
motion in R.A. and Dec. each with their estimated mean errors as determined
from internal disagreements on the several plates used. In each case I have
applied appropriate corrections to reduce the motion from relative to absolute
though admittedly, for very faint stars, measured relative to stars of the
17th and 18th photographic magnitude, these corrections are little more than
guesswork. The last column gives the number of the previous publication were
further details about the about the measures have been published. Here 'ApJ'
refers to the list of proper motions published by Miller and myself for the
HZ stars (1951 Ap.J., 114, 488.) and 'ms' refers to the revised, or new values
for proper motions not yet published.
