Beginning of ReadMe : I/73 HKE Sydney Catalog (Eichhorn+ 1983) ================================================================================ Catalogue of 20457 star positions obtained by photography in the declination zone -48 to -54°(1950) Eichhorn H., Googe W.D., Lukac C.F., Murphy J.K. <Astron. J. 88, 546 (1983)> =1983AJ.....88..546E =1983yCat.1073....0E ================================================================================ ADC_Keywords: Positional data ; Photographic catalog Abstract: The methods for constructing a catalogue of 20457 star positions for the epoch 1964 between -48 and -58deg 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 position. A selection of about 2 faint Astrographic Catalog (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 a catalogued position estimate based on 2 images is 0.12'' in either coordinate. Description: The plates were exposed on the Taylor, Taylor and Hobson catalogue camera of the Sydney Observatory, always west of the pier, from Feb.13 to Oct.29, 1964. Each plate covers an area of 6x6deg with a scale of 116.1''/mm. The declinations of the plate centers were always -51deg (in 1950 equinox). The average epoch is 1964.47 (see table 1 of the paper for the epochs of the individual fields).
