Caption: Figure A1.
Model fits and residuals for T CrB (part 1 of 2). The upper panel of each subplot shows the squared visibility V2 vs. the baseline length, with data points colored by baseline pair and the best-fit limb-darkened disk model (scaled by ﹩{V}_{0}^{2}﹩) shown as black dots. The lower panel shows residuals in units of σ; green shading indicates the ±1σ region and yellow shading the ±3σ region.
