Description:
The third annual catalog of the Tokyo PMC is presented for 5748 stars
which had been observed at least two times in the year 1987 period,
that is, from January 1, 1987, to December 31, 1987. The positions of
the stars given in the catalog are those at the mean epoch of
observations. The coordinates of the catalog are referred to the
equinox and equator of J2000.0, based on the FK5 system.
The mean trends of the observed positions minus FK5 positions for the
FK5 basics stars are constructed and compared with those of the Tokyo
PMC 86 catalog.
The part I of the catalog contains the positions of 1017 FK5 basics
(=FK4 stars ), 533 FK4 Suppl. stars, 2421 AGK3R stars, 1167 OB stars,
113 NPZT stars, and 84 SAO stars, and the part II of the catalog
contains the positions of 413 SAO stars for occultation studies.
These two parts were merged into a single pmc87 file.

Historical Notes:
* 30-Sep-1991: the catalogue was supplied to CDS by Shiro Nishimura;
the reformatting of the data were carried out at the Astronomical
Data Analysis Center of the National Astronomical Observatory, Japan.
* 20-Feb-1996: Documentation standardized, using the same description
as catalog I/198 by S.Nishimura [ADAC/NAOJ], from 01-Sept-1993
