| Kharkiv Institute of Radio Astronomy UTR-2 Catalogue |
In early 70-th the unique low-frequency radio telescope UTR-2 was created at the Radioastronomical Observatory near Grakovo, Kharkiv region (now- S. Ya. Braude Radioastronomical Observatory, it is the subdivision of the Institute of Radio Astronomy of NASU). At present the UTR-2 is the greatest and the most perfect tool at the decameter band of the wavelengths. Its characteristic features are the great linear sizes (2x1 km) and the effective area (150 000 m2), the high directivity (the beamwidth is 25’ at the frequency 25 MHz), the low level of sidelobes, and the wide frequency range (8-35 MHz), the many-beaming, the electronic control of the beam at the wide sector in both coordinates, the great dynamic range, the interference stability, the reliance in the operation.
Combination of the high efficiency of the radio telescope UTR-2 and the new registration facilities allowed in last time to carry out the large volume of investigations in different programs with obtained new results. The most of Universe’s objects from the nearest vicinity of the Earth, the Solar system, our Galaxy to the most distant radio galaxies and quasars are accessible for studies by the decameter radio astronomy methods.
At present the most complete catalogue of the extragalactic sources of the Northern sky (near 4000 objects) is compiled at the decameter band. The analysis of the statistical complete survey of the extragalactic sources permitted to determine and classify their radio spectra, to reveal great variations of the low-frequency spectral indices, to identify the catalogued objects.
The catalogue of extragalactic sources UTR-2 is on-line at the site of Institute of Radio Astronomy.
| Institute of Astronomy of Kharkiv National University Catalogue XPM |
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 < 19 mag. 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 1 mas yr?1. The XPM Catalogue will be available via CDS in Strasbourg during 2010. The generated catalogue contains the International Celestial Reference System positions of stars for the J2000 epoch, original absolute proper motions, as well as B, R, J, H and K magnitudes. A comparison of the proper motions obtained in this work with the data of other recent catalogues of quasars was fulfilled.
