Top: cross section (column 1300) of the SOSS 2D image of the WASP-80 field. The photometric aperture used to extract the spectrum in the additional reduction of the first and second-order traces are highlighted by the light-red and orange boxes. The imaged field star is highlighted by the light-blue box. The red, orange, and blue lines show the PSF model used to model the distribution of starlight across the field. The PSF model was used to estimate photometric contamination inside the aperture of each trace and repeated for each column to construct a decontamination model to accurately measure eclipse depths in the additional reduction. Bottom: same as top panel, but for column 1575, which is the last column used in the extraction of order 2. The contamination from the imaged field star on the order 2 extracted flux is <1% at this column.
