The Radio Fundamental Catalogue, data release rfc_2026c, contains positions, estimates of correlated flux density, and images of 23866 compact extragalactic radio sources from reanalysis of 1236 VLBI experiments at the VLBA, LBA, EVN, VERA, and IVS under 79 absolute astrometry programs during 1994-2026, as well as from all available geodetic VLBI observing sessions since 1980.04.11 through 2026.09.03, in total, 23259 experiments. The positions were derived from a single least square solution using 30,704,191 fused group delays.
