Mass distributions with best-fit values of all SANE model frames fit to the EHT2017 (blue) and EHT2021 (orange) synthetic data generated from frame 20 of the SANE model with a_* = 0.5 and R_high = 80. The six panels correspond to the six values of R_high in the model library, and the black hole spin is on the horizontal axis. The red dashed line indicates the true mass of the input model (encircled). The models corresponding to the distributions with annotation “ACC” and “REJ” were accepted and rejected, respectively, by the average image scoring procedure.
