Optical data for XTE J1814−338. Measurements taken on 2003 June 6 and 7 are plotted as squares, and those from the nights of 2003 June 21 and 24 are shown as triangles (errors are on the order of the symbol size). The observed fluxes were dereddened assuming a Galactic extinction of ﹩A_{V}=0.71﹩. The emission predicted by an X‐ray–heated accretion disk model is plotted as a dashed line. For this model, we used a source distance of 8 kpc with Galactic extinction and minimized χ² by setting ﹩\mathrm{cos}\,i=0.6﹩. Note that since these parameters are degenerate, the inclination angle fitted here is not well constrained. The I‐band flux (9000 Å) lies well above the model prediction.
