Parsec structure and properties of the jet of 3C273. Results of Space   VLBI data processing
  We present result of processing of data of ground-space VLBI experiment titled W068. Particularly, one part of data of that observational session is successfully processed. These data were obtained on 2000 March 17 between 9:00 UT and 10:30 UT. 10 antennas of American interferometer VLBA (Very Long Baseline Array) and Japan satellite VSOP (VLBI Space Observatory Programme) were involved into this experiment. Moreover, 27 antennae of VLA (Very Large Array)} were used as an additional ground antenna. Data were transferred from archive of the NRAO (National Radio Astronomy Observatory, USA)and processed with the software titled 'Astro Space Locator' (ASL for Windows). The main result of this processing is the image of the quasar titled 3C273 with high resolution and high accuracy. Using this image, we make some conclusions about the radio structure of jet of this object. Our result is not in conflict with other results of processing of the Space VLBI data for 3C273 published earlier with many authors. We could add some new aspects into that results. The reconstructed images of 3C273 for 6 centimeter wavelength range and values of some parameters of this source are presented.
