... The reduction system of observations FADPS (description in Russian) (Flexible Astronomical Data Processing System) for data of wide-band receivers of the first observation cabin of the radio telescope RATAN-600 had been created under the Unix-like operational system DEMOS for computers of the SM-1420-type (PDP/11) in 1987 for observation analysis and estimates of coordinates and flux densities of radio sources. ...

... The source exhibits a mas-scale structure which, according to the USNO multi-epoch monitoring at 2.3 and 8.4 GHz over the period from 1994 July through 1998 April, undergoes considerable changes in the brightness distribution and positions of the major structural features. Our image is qualitatively consistent with the structural pattern of the source. ... We note a difference of ~90 in position angles of secondary components in our image and the 5 GHz VLBI image by Shen et al. 1998). ...
