The Radio Fundamental Catalog
DOI: 10.25966/dhrk-zh08
The Radio Fundamental Catalog (RFC) provides
- precise positions
with milli-arcseconds accuracies
- estimates of correlated flux
densities at baselines 1000–8000 km, and
- maps
of thousands of compact radio sources produced by analysis of
all available very long baseline interferometry (VLBI) observations
under absolute astrometry and geodesy programs. The Radio Fundamental
Catalogue defines the reference and establishes the foundation for
space geodesy, space navigation, differential astrometry, studies
of AGN jets and cores, and analysis of the radio loud AGN population.
rfc_2024d catalogue of compact radio sources. This catalogue
is currently the most complete. It has
21,942 objects. The catalogue includes all
sources observed with VLBI under absolute astrometry and geodesy programs
from 1980.04.11 through 2024.12.03. Also
127,987
images in FITS format
of 20474
radio sources are
available from the database of brightness distributions
and images of compact radio sources.

and include DOI 10.25966/dhrk-zh08 of the dataset in the acknowledgement section.
Change log
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
and corrected.
