GMOS R150 spectral light curves and residuals for observation 3. Transit light curves are shown after removal of systematics and normalization, overplotted with the best-fitting transit models from Mandel & Agol (2002). In each case, the spectral light curves are plotted with longer-wavelength bins at the bottom, and each light curve has an arbitrary flux offset for clarity. Photometric uncertainties have been rescaled with f in the residuals plot. The data used to create this figure are available.
