Image Details
Caption: Figure 1.
Left panels: the normalized, phase-folded transit light curves of WASP-43 b from the 2.4 m and 1 m TNT observations in the SPEARNET telescope network, shown as gray circles. The best-fitting model from TransitFit is displayed as a solid line. Right panels: residuals of the light curves after model subtraction. Both the light curves and residuals are vertically offset for clarity. The corresponding residuals and the mean residual values (﹩{\bar{x}}_{\mathrm{res}}﹩) with clear offsets are displayed in the right panel.
