Left: secondary eclipse data of WASP-12b obtained with the NOT and the EDs turned on. Black circles and error bars correspond to the photometric data. The red continuous line shows the best-fit secondary eclipse, in ppt. For the most prominent eclipse we show raw photometry (gray squares), along with the combined best-fit model (transit times detrending) (blue solid line). Right: χ² maps for different scaling factors. The thick black line corresponds to the χ² values obtained for different eclipse depths. The red vertical line indicates the minimization of χ², and the black solid vertical line, along with the two dashed lines, indicate the best-fit MCMC results and a ±2σ contour.
