First epoch plates for a proper-motion program were taken in 1969-1970 using
the 70/100/210 cm Double Meniscus Maksutov Astrograph at Estación
Astronómica de Cerro El Roble de la Universidad de Chile by H. Potter and
A. Lokalov. The 164 southern hemisphere areas of the program were selected
by A.N. Deutsch, according to the criterion of having enough galaxies to be
used as a local reference frame. Although the proper motion program
assumes a minimum time-base of 20 years, in August 1985 we began taking
second-epoch plates of the areas south of declination , with the
purpose of searching for large proper motion stars. These southern areas
were chosen because the Bruce Proper Motion Survey, the principal source
south of declination
of the LHS proper motion Catalogue (Luyten
1979), reaches only to about m=16, and our plates limit is
approximately m=20. A time-base of 15 to 20 years has been shown to be
adequate for determining, from plates with scale 100 arcsec/mm, proper
motions equal to or larger than 0.15 arcsec/year for stars fainter than 10
and brighter than 20 photographic magnitude.
The present work is the fifth part of a program determining proper motion of
southern stars. In this part, we do not include the Luyten Catalogue stars found in this
survey. The work includes 21 areas, each with two plate pairs. Some areas have a fraction
of the degrees flat field overlapped. Figure 1 (click here) shows the distribution of
the searched areas on the sky. Table 1 (click here) gives the coordinates of
the centers of the areas for 1950.0 and the time-base in years
corresponding to each plate pair.
