Comments.
The topocentric positions are given for the equinox J2000.0 and
based on a reference frame defined by the PPM and SAO reference
stars (Roser & Bastian 1991). The SAO stars were transformed from
FK4/B1950.0 to the FK5/J2000.0 system in the standard way
(Roser & Bastian 1991) and were only used
for declinations < -10 degrees.
Values in the column 11, 12 are the standard deviations
of the coordinate residuals (least-squares plate solution
minus star-catalogue position) of the reference stars used
in the plate reduction.
