Upper row: photon count residuals between the data and best-fit model, in sigma units on a 0.̊125-pixel grid, in the 0.4−100 GeV band, with the DNM template from the dust A_VQ (left), τ₃₅₃ (middle), or radiance (right). Lower row: dust residuals between the data and best-fit model, in sigma units, for the fit in A_VQ (left), τ₃₅₃ (middle), and radiance (right). The grey contours outline the CO clouds at the 2.3 K km s^-1 level.
