The Radio Fundamental Catalogue, data release rfc_2026a, contains positions, estimates of correlated flux density, and images of 21950 compact extragalactic radio sources from reanalysis of 1206 VLBI experiments at the VLBA, LBA, EVN, VERA, and IVS under 75 absolute astrometry programs during 1994-2024, as well as from all available geodetic VLBI observing sessions since 1980.04.11 through 2026.03.10, in total, 22539 experiments. The positions were derived from a single least square solution using 29,486,375 fused group delays.
