Upper left: vs. M_BH for the Rev sample. Red and blue filled circles indicate sources with ṁ in the ranges (0.0098–0.035) and (0.42–0.86), respectively, thus with average accretion rates of  ⟨ ṁ ⟩  = 0.016 and 0.64, respectively. While the black filled circles show the for the sources with different accretion rates. The red and blue lines indicate the expected Model A relations for the two accretion rates. Upper right: CAIXAvar (20 ks) and Model A predictions (color code as before). Lower left and right: Model B predictions.
