The Radio Fundamental Catalogue, data release rfc_2026b, contains positions, estimates of correlated flux density, and images of 22839 compact extragalactic radio sources from reanalysis of 1227 VLBI experiments at the VLBA, LBA, EVN, VERA, and IVS under 78 absolute astrometry programs during 1994-2026, as well as from all available geodetic VLBI observing sessions since 1980.04.11 through 2026.06.07, in total, 22911 experiments. The positions were derived from a single least square solution using 30,190,420 fused group delays.
