with milli-arcseconds accuracies
estimates of correlated flux
densities at baselines 1000–8000 km, and
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.
The Radio Fundamental Catalog is currently under active development.
The current version of the catalogue rfc_2022d is available.

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
