Description:
  This catalog contains a field of 2.8 square degrees centered on Kapteyn 
  Selected Area 141 (l=245, b=-86). The center of field was near SAO 166815 
  (Bok I 174 B) at 01h05m11s -29d33'12"(1950). The covered ranges were
  01h01m30s< RA < 01h09m30h and -30d20' < Dec < -28d35'(1950). Photographic 
  V magnitudes and B-V colors of 640 stars were measured in Region I. Data
  were card punched at the Australian National University on an Univac
  1100/82.  The coordinates were determined by Kavan U. Ratnatunga from 
  PDS scans of the region on UKSTU Schmidt plate J6657S (taken on 
  03-Jan-1981) and visual cross identifications were given with the 
  published finding chart. The coordinate calibration used the positions of 
  SAO stars.  Estimated rms accuracies for the following measurements are:
    Visual Magnitude: 0.03 mag
    B-V colors      : 0.05 mag
    Positions       : 1    arc second
