I/248 Tokyo Photoelectric Meridian Circle Catalog 90-93 (Yoshizawa+ 1997)

The Tokyo PMC Catalog 90-93: Catalog of Positions of 6649 Stars Observed
in 1990 through 1993 with Tokyo Photoelectric Meridian Circle

Description:
The sixth annual catalog of the Tokyo PMC is presented for 6649 stars
which were observed at least two times in January 1990 through March
1993. The mean positions of the stars observed in the above period are
given in the catalog at the corresponding mean epochs of observations
of individual stars. The coordinates of the catalog are based on the
FK5 system, and referred to the equinox and equator of J2000.0. The
mean local deviations of the observed positions from the FK5 catalog
positions are constructed for the basic FK5 stars to compare with
those of the Tokyo PMC Catalog 89 and preliminary Hipparcos results of
H30.
The catalog contains the positions of 1180 basic FK5 stars, 322 FK4
Suppl. stars, 3132 AGK3R stars, 141 OB stars, 252 NPZT stars, and 1601
SAO stars observed with the Tokyo Photoelectric Meridian Circle in the
1990 to 1993 periods based on the FK5 system. The positions of the
stars are given for the mean epoch of the observations of individual
stars referring to the equinox and equator of J2000.0.
The values of (O-C)s in the catalog are calculated by using the
positions given in the source catalog, and by evaluating those at the
mean epoch of observations of each star, with the equinox and equator
at the mean epoch. The magnitudes of the stars given in the catalog
can be transformed into the V-magnitude of the standard UBV system by
the equation :
V = V(TPMC) + 0.063(B-V) - 0.045.

Note (1): Besides obvious standard designations,
AGK3 : star numbers are composed as DDNNNN,
H2O : Unpublished list of H2O masers and related objects; star numbers
are preliminary number in an observing list,
OB : "Catalog of O-B Stars Observed with Tokyo Meridian Circle"
(Yasuda+ 1986), N.B.: star numbers are not the catalog numbers
but the OBSNO's deducted by 15000 (OBSNO: preliminary star
number in an observing program),
PZT : "Northern PZT Star Catalog" (Yasuda+ 1982), N.B.: star numbers
are not the catalog numbers but the OBSNO's, which are
preliminary star numbers in the Northern PZT Star list.
Note (2):
BD number for Dec. > -23 degrees, and CD number for Dec. < -23
degrees, component designations "p, s, x" are those used in PPM
catalogues (<I/146>, <I/193>, <I/208>)
Note (3):
An asterisk at byte 134 indicates that the entry is an unresolved double
star which has two AGK3 numbers, i.e. "+41 1873" and "+41 1874".
