Overview of the data recorded by the NIRISS detector, based on a stack of out-of-transit integration images. The spectral orders are labeled; a different color scale is applied to enhance the visibility of the faint fourth order (gray rectangle). Regions used for scaling the model background and the location of the background step are highlighted (red and green). Areas identified via sigma clipping as containing signal (rather than background) are masked (white). The locations of two potential zeroth-order contaminants overlapping with the spectral traces are also indicated. For better visibility, these regions are shown with a separate color scale and an enlarged box (2 × ∆x) compared to the area that was interpolated over.
