Description:
The catalog contains 6125 stars brighter than B=17.5, V=17.0 in the
south galactic cap. The data have been obtained using the UK Schmidt
telescope between 1975 and 1981. The plates were measured on the
GALAXY machine at RGO. External errors of the parallaxes range between
-/+0.012 and -/+0.017 arcsec according to magnitude. Internal proper
motion errors range from -/+0.006 and -/+0.008 arcsec. In addition to
the positions, proper motions, and parallaxes, the photometric data
include B and V.
Nomenclature Notes:
The stars from this catalogue are named "RGO" followed by the number
in "RGO" column of "catalog" file.

Note (1): The quality code is blank for satisfactory data; it takes otherwise
the following basic values:
1 = Abnormal errors in Series B
2 = Abnormal errors in Series A
4 = Inconsistent results between the two Series
The remaining codes are combinations of these (e.g. 3 = 1 + 2)
