Pulkovo, ser. 2 86 4-158 1986 1986TrPul..86....4B Positional data The Catalogue SPF2 was obtained from observations of the fundamental FK4 stars as a reference stars for SRS, BS and DS star. Observations were made by Pulkovo observers in the declination zone -42 to -90 and +16 to -16 degrees using Repsold Meridian Circle of the Cerro Calan Observatory (Santiago, Chile) from 1963 to 1968.
They worked in closed cooperations with their Chilean colleagues who observed other declination zones. In total 15160 observations were made of FK4 stars. The reductions of observations were made by the quasi-absolute method proposed by M.S.Zverev (1969). Investigations were carried out of the systematic differences of type "E-W" as well as of the personal equations. Also differences of type "Upper - Lower culmination" were investigated. All these corrections were applied to the observations. The mean error of the single observations reduced to the equator is +/- 14.0 millisecond of time. The mean error of the position of a single star reduced to the equator is +/- 2.8 millisec of time (each position in the middle are consists from 25 observations). The main results of the systematic errors were published by Zverev and Naumova.
