VLBI monitoring of the structure of the ICRF sources - The Bordeaux VLBI Image Database

The extragalactic radio sources that make up the International Celestial Reference Frame (ICRF) can exhibit extended and time-variable brightness distributions (or structures) on VLBI scales, setting limits on the accuracy of the astrometric source positions determined from the VLBI measurements. For this reason, regular VLBI observations are organized
