Astrometry comparison between 3 and 1.4 GHz VLBA data for 30 VLBA sources (Herrera Ruiz et al. 2017). Median and standard deviation for ΔR.A. and Δdecl. are reported in the panel. The positions of sources detected at 3 GHz are in excellent agreement with the positions as reported in the VLBA-COSMOS 1.4 GHz survey (Herrera Ruiz et al. 2017).
