        <p:para><![CDATA[
   This catalog of 3356 faint stars was derived from meridian circle
   observations at the Bergedorf and Heidelberg Observatories. The
   positions are given for the equinox 1950 on the FK3 system. The stars
   are mainly between 8.0 and 10.0 visual magnitude. A few are brighter
   than 8.0 mag. The lower limit in brightness resulted from the visibility
   of the stars.]]></p:para>
        <p:para><![CDATA[
   All stars were observed at both the Heidelberg and Bergedorf
   Observatories. Normally, at each observatory, two observations were
   obtained with the clamp east and two with the clamp west. The mean
   errors are comparable for the two observatories with no significant
   systematic difference in the positions between them. The mean errors of
   the resulting positions should be approximated 0.011s/cos(dec) in right
   ascension and ).023" in declination.]]></p:para>
        <p:para><![CDATA[   The proper motions were derived from a comparison with the catalog
   positions with the positions in the AGK2 and AGK2A with a 19 year
   baseline and from a comparison of new positions with those in Kuestner
   1900 with about a fifty year baseline.]]></p:para>
        <p:para><![CDATA[   The magnitudes were taken from the AGK2. Most spectral types were
   determined by A. N. Vyssotsky. A few are from the Bergedorfer
   Spektraldurchmusterung.]]></p:para>
