Normalized distribution of the difference r(G)−r. The value of r is predicted from G minus measured r for LQAC-5 quasars cross-identified with Gaia EDR3, normalized by the formal error added in quadrature to an intrinsic dispersion term, which we find to be σintr. = 0.21 mag, consistent with expectations from AGN variability. The solid black line shows a normal distribution with mean of zero and standard deviation of unity.
