   The catalog contains the right ascensions and declinations (equinox B1900.0
   and epoch B1955.0) of 502 stars in a region of about 1.5 degrees square in
   the Pleiades cluster, centered on Eta Tau.  These coordinates have been
   derived from measurements of stellar images obtained with 65 exposures of
   various durations on 14 photographic plates with two telescopes at McCormick
   Observatory and Van Vleck Observatory.  The plates were reduced by the
   plate overlap method, which resulted in a high degree of systematic
   accuracy in the final positions.  Data in the machine version include
   Hertzsprung number, color index, photovisual magnitude, right ascension and
   declination and their standard errors, proper motion, and differences
   between the present position and those of Koenig (1924).  Data for
   exposures, plates, and images measured, present in the published catalog,
   are not included in the machine version.]]></p:para>
