I/44 Second Cat of Fundamental Stars (SPF2) (Baturina+ 1986)

Catalogue of Coordinates of Reference Faint, Bright and Double Stars
South of -47 Degree and Corrections to FK4 Positions as Observed by
Pulkovo Astronomers with the Meridian Circle at the Cerro-Kalan
Observatory (Chile) in 1963-1968

ADC_Keywords: Meridian observations ; Positional data
Description:
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.
Introduction:
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.
