Beginning of ReadMe : I/90 Positions of 502 Stars in Pleiades Region (Eichhorn+ 1970) ================================================================================ Accurate Positions of 502 Stars in the Region of the Pleiades Eichhorn H., Googe W.D., Lukac C.F., Murphy J.K. <Mem. Roy. Astron. Soc. 73, 125 (1970)> =1970MmRAS..73..125E ================================================================================ ADC_Keywords: Positional data ; Clusters, open ; Regional catalog Description: The catalog contains the positions (equinox B1900.0 and epoch B1955.0) of 502 stars in a region of about 1.5 degrees square in the Pleiades cluster, centered on Eta Tau. These coordinates have been derived from measurements of stellar images obtained with 65 exposures of various durations on 14 photographic plates with two telescopes at McCormick Observatory and Van Vleck Observatory. The plates were reduced by the plate overlap method, which resulted in a high degree of systematic accuracy in the final positions. Data in the machine version include Hertzsprung number, color index, photovisual magnitude, right ascension and declination and their standard errors, proper motion, and differences between the present position and previous works. Data for exposures, plates, and images measured, present in the published catalog, are not included in the machine version.
