Beginning of ReadMe : I/78 SPF3 Catalogue (Loyola+ 1974) ================================================================================ Third Santiago-Pulkovo Fundamental Stars Catalogue (SPF3) Loyola P.R., Shishkina V.N. <Publ. Dept. Astronomy Univ. of Chile 2, 159 (1974)> =1974PDAUC...2..159L ================================================================================ ADC_Keywords: Meridian observations ; Positional data ; Stars, fundamental Description (from Wayne H. Warren Jr.): The "Third Santiago-Pulkovo Fundamental Stars Catalogue (SPF3)" is a catalogue of right ascensions (the primary datum) of 671 fundamental bright stars, as measured with a Zeiss broken transit instrument at Cerro Calan Observatory in Chile. The observations were made in series consisting of 70 stars observed along the meridian from +42deg to the pole in upper culmination and from the pole to -70deg in lower culmination; the program consisted of 231 series of observations. In addition to the final reduced right ascensions for the program stars, the catalogue contains cross identifications to the N30 (Morgan 1952) and FK4 (Fricke et al. 1963) catalogues, visual magnitudes, approximate declinations (equinox 1950.0), mean epochs of the observations, and mean errors of the determined right ascensions. This document describes the machine-readable version of the SPF3 catalogue as distributed by the Astronomical Data Centers. It is intended to enable users to read and process the catalogue data without unnecessary problems and guesswork. The source reference should be consulted for details regarding the instrument characteristics, measurements, reductions, and comparisons with other catalogues.
