ADC_Keywords: Positional data; Meridian observations
Description:
This catalog contains positions and magnitudes for 1577 stars with
visual magnitudes brighter than 11.0. The observations were made with
the 7-inch transit circle at the Copenhagen University Observatory from
July 1981 to May 1982. The positions are reduced to the FK4 system for
each night and over the whole meridian. The mean errors of the catalog
entries are: in right ascension 0.006 seconds/cos(declination); in
declination, 0.10"; and in magnitude, 0.06mag.
The catalog contains 425 FK4 stars used for the adjustment to the FK4;
167 stars from the AGK3 zones +88deg. and +89deg.; 115 stars from the
zone around the North Galactic Pole; stars from several PZT zones; some
faint GC stars; reference stars for radio fields; and a few stars from
earlier Brorfelde programs. The internal errors of a single observation
are for right ascension, 0.0138 seconds/cos(delta), for declination,
0.216", and for the magnitude, 0.132 mag.
