37 ICRF2-Gaia transfer sources specifically scheduled in some R&D and RDV sessions. The square means the source was scheduled on the given date and the dotted square means the source observations were successful and were used in a VLBI data solution for the latest GSFC quarterly solution. The most successful sessions are those with larger antennas (RD1306, RD1404, and RD1504).
