Construction of a celestial coordinate reference frame from VLBI data

  • O. A. Titov


A large number (∼2 million) of VLBI observations have been reduced in order to refine the measured coordinates of the observed radio sources. The data reduction was carried out in the OCCAM package using the least squares colocation method. Corrections to the coordinates of 642 objects were derived. The accuracy of the catalog is no worse than 0.2 milliseconds of arc for stable sources.
