ALMA-only flux density measurements (Goddi et al. 2021) versus intra-site VLBI flux densities obtained during the EHT campaign, as reported in Table 2. The available data points correspond to observations of 3C279, 3C273, Centaurus A, OJ287, 1055+018, J1924-2914, Sgr A*, NRAO 530, and M87. Left panel: the dashed lines scale ALMA-only flux densities down by 0.8 (red) and 0.72 (blue), to approximately match ALMA-APEX and JCMT-SMA measurements. Right panel: after correcting for 7% ALMA VLBI losses and scaling all VLBI flux densities up by 25%, we find consistency with ALMA-only data for all the sources.
