Abstract:
We combined data from the Two-Micron All Sky Survey (2MASS) and
USNO-A2.0 catalogues in order to derive the absolute proper motions of
about 280 million stars distributed all over the sky excluding a small
region near the Galactic Centre, in the magnitude range 12<B<19mag.
The proper motions were derived from the 2MASS Point Sources and
USNO-A2.0 catalogue positions with a mean epoch difference of about 45
years for the Northern hemisphere and about 17 years for the Southern
one. The zero-point of the absolute proper motion frame (the 'absolute
calibration') was specified with the use of about 1.45 million
galaxies from 2MASS. Most of the systematic zonal errors inherent in
the USNO-A2.0 catalogue were eliminated before the calculation of
proper motions. The mean formal error of absolute calibration is less
than 1mas/yr.
Description:
The final version of the XPM catalogue contains about 314million
stellar positions and absolute proper motions and covers the whole
celestial sphere without gaps in the magnitude range 10<B<22mag.
The general procedural steps were followed as for
XPM, but some of these were performed on a more sophisticated level.
The XPM-1.0 catalogue contains the star positions, the proper motions
and the Two-Micron All-Sky Survey (2MASS, Cat. II/246) and United
States Naval Observatory (USNO, Cat. I/252 + I/284 + I/315) photometry.
The analysis of stellar positions and proper motions of the XPM
catalogue, were shown to have an ambiguity of rotation relative to the
LQAC quasars and ICRF2 sources less than 0.2mas/yr. It is concluded
that the XPM catalogue is the independent realization of the ICRS in
the optical and near infrared wavelengths in the sense of obtaining of
proper motions. The absolute proper motions of XPM stars were compared
with the similar data from the HCRF (Hipparcos Celestial Reference
Frame) modern catalogues. The proper motions of stars in these
catalogues were shown to have the appreciable random and systematic
errors.
The random errors are estimated to be < 60mas in RA/Dec for the stars
fainter than B=12mag, and the random errors of absolute proper motions
are slightly different for the northern and southern hemispheres:
3-8mas/yr for the North and 5-10mas/yr for the South.
