As in Fig. A.1 but for those sources corrected only by point sources correction. AFGL 5379 and IRAS 16279-4757 are mispointed targets for which the semi-extended 3 × 3 correction could not be applied as they are located in one of the outermost spaxels. The well-pointed object OH 32.8-0.3 shows, for unknown reasons probably related to problems during the observations, negative fluxes in some of the 3 × 3 central spaxels, so the semi-extended 3 × 3 correction produced a wrong final 1D spectrum.
