Notes. The reference is presented in Col. #1, the source profile used in Col. #2, and the published size estimate in Col. #4 (where R = radius of a uniform disc, RV = scale radius of a Shakura-Sunyaev accretion disc, σV and FWHM are resp. the standard deviation and the full width at half maximum of a Gaussian). These quantities have been converted to half-light radius R1/2 to allow comparison between profiles. Columns #6 & #7 provide the average mass of microlenses (⟨M⟩) used in the microlensing simulations and information regarding the velocity prior.
