Figure 1: Layout of background extraction swaths on a sample SWP high-dispersion image. Lines running in vertical (spatial) direction are the Pass 1 extractions. Raw fluxes are sampled along these lines that are within the target ring and outside or between the echelle orders. The reconstructed background solutions created in Pass 2 are placed in the positions of the echelle orders (horizontal lines).
