Cosmics processing applied to epoch 2 of WASP-76. Top subpanels show F(t) – F_comp divided by σ_Fcomp (black) and σ^meas(t) (green), with α_cosm plotted as a red line, in a sample exposure whose flux spectrum is shown in the bottom subpanels. The red pixel in the top block (together with adjacent pixels) is corrected because it deviates with respect to both its own uncertainty and to the standard deviation over adjacent exposures. The pixel in the bottom block is not corrected because it could result from photon noise in the exposure.
