Reconstructed specific intensity of GJ 1214, plotted alongside stellar models. Upper panel: flux spectrum from GJ 1214 and the best-fitting models. Middle panel: specific intensity close to the center of the disk, ﹩\mu =0.9﹩. Lower panel: specific intensity close to the limb of the disk, ﹩\mu =0.1﹩. Note that the specific intensity is given relative to the average specific intensity across the entire disk. Low relative intensity in the center of the disk and high relative intensity at the limb of the disk indicates a flat intensity distribution, and a higher value at the center and lower at the limb indicates a steeper contrast difference.
