SMARTS & Euler R-band monitoring of WFI J2033-4723

Using a Bayesian Monte Carlo technique, we analyze the microlensing signal to obtain a measurement of the size of this system's accretion disk of log(r_s_/cm)=15.86_-0.27_^+0.25^ at {lambda}_rest_=2481{AA}, assuming a 60{deg} inclination angle.

We confirm previous measurements of the BC and AB time delays, and we obtain a tentative measurement of the delay between the closely spaced A1 and A2 images of {Delta}t_A1A2_=t_A1_-t_A2_=-3.9_-2.2_^+3.4^d. We conclude with an update to the Quasar Accretion Disk Size-Black Hole Mass Relation, in which we confirm that the accretion disk size predictions from simple thin disk theory are too small.
