Radio Fundamental Catalog
The Radio Fundamental Catalog (RFC) provides
for thousands of compact radio sources produced by analysis of
all available very long baseline interferometry (VLBI) observations
under absolute astrometry and geodesy programs. This catalogue forms the
backbone of astrometry with the highest accuracies for various applications,
such as differential astrometry, a pool of phase calibrators, a pool of
sources for geodetic VLBI, association with active galaxy nuclea (AGN)
objects observed in other wavelengths, ties with optical and infrared
astrometric catalogues, morphology study of AGNs, statistical analysis of
radio-loud AGN population, and many others.

with milli-arcseconds accuracies
- estimates of correlated flux

The Radio Fundamental Catalog is currently under active development.
The current version of the catalogue rfc_2023a is available.

rfc_2023a catalogue of compact radio sources. This catalogue
is currently the most complete. It has
21,906 objects. The catalogue includes all
sources observed with VLBI under absolute astrometry and geodesy programs
from 1980.04.11 through 2023.03.09. Also
images in FITS format
radio sources are
available from the database of brightness distributions
and images of compact radio sources.
The catalogue is updated on a quarterly basis because 1) new data are available;
2) old data are reprocessed with advanced software; 3) errors are found
