Broadband and spectroscopic secondary eclipses observed as part of the NIRISS/SOSS phase curve of WASP-121b, extracted with the NAMELESS pipeline. The light-curve fit (black line) of the broadband order 1 light-curve (λ = 0.85–2.83 µm) is shown, along with the data binned at a resolution of 25 integrations per bin for visual clarity. The 122 light curves of the second order and 361 light curves of the first order are binned into three and six light curves, respectively (coloured points).
