VLBI Position Measurements
Listed in IVOA Registry (Virtual Observatory)
A large number (~2 million) of VLBI observations have been reduced in order to re ne the measured coordinates of the observed radio sources.
Description
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.
