Abstract (from CDS):

The Photoelectric Astrolabe Mark I (PHA I) has been revised with a new combined prism which could work as an almucantar with zenith distance of 45°, to measure continuous declinations at the latitude of Irkutsk, Russia (φ= 52.2deg). The PHA I has been working at the astronomical base of VS NIIFTRI in Irkutsk since Nov. 1995 based on an international cooperation agreement of near 4 years for star catalogue and EOP measurements. The first observing program was ended in June 1997, giving corrections in both right ascension and declination to 200 stars with no blind zone in declination determination, which most astrolabe catalogues in the world usually would have.
