Our joint analysis provides robust constraints on the extent of the X-ray continuum emission region and the projected area of the accretion disk. The best-fit half-light radius of the soft X-ray continuum emission region is between 5x1013 and 1015cm, and we find an upper limit of 1015cm for the hard X-rays. The best-fit soft-band size is about 13 times smaller than the optical size, and roughly 7GMBH/C2 for a 2.8x108M black hole, similar to the results for other systems. We find that the UV emitting region falls in between the optical and X-ray emitting regions at 1014cm<r1/2.UV<3x1015cm. Finally, the optical size is significantly larger, by 1.5σ, than the theoretical thin-disk estimate based on the observed, magnification-corrected I-band flux, suggesting a shallower temperature profile than expected for a standard disk. Description: We monitored SDSS J0924+0219 for ten seasons (2003-2014) in the R band using the SMARTS 1.3m telescope with the ANDICAM optical/infrared camera, and for three seasons (2010-2013) using the 1.2m Euler Swiss Telescope as a part of the COSMOGRAIL project. SDSS J0924+0219 was observed at 10 epochs between 2009 August and 2011 August using the Wide Field Camera 3 (WFC3) on board the HST. We monitored SDSS J0924+0219 in X-rays using the ACIS imaging spectrometer on the Chandra X-Ray Observatory for six epochs between 2005 February 24 and 2010 October 5.
