Catalogue of 20457 Star Positions Obtained by Photography in the Declination Zone -48 deg to -54 deg (1950),

Abstract

The methods for constructing a catalogue of 20457 star positions for the epoch 1964 between -48 deg to -54 deg declination are described. The positions were obtained by the overlap method, and images generated by a coarse diffraction grating were employed to control magnitude related effects on the positions. A selection of about two faint AC stars per square degree was included to serve as material for the eventual determination of magnitude effects on the AC positions. The standard error of catalogued position estimate based on two images is 0.12 sec in either coordinate.
