One-dimensional spectra extracted for three different targets in the THROES catalogue following the procedures described in Sect. 3 (red). The flux corrections and apertures have been chosen depending on the source extent and its location in the 5 × 5 spaxels FoV of PACS. For comparison, we show the corresponding spectrum obtained in each case from the central spaxel before post-processing (blue). At the top right corner of each box, we show a layer of the FinalCube with the 5 × 5 spaxels of the PACS spectrometer of the observation. The crosses indicate the spaxel from which the spectra were taken; a black cross means that both spectra were extracted from the central spaxel. The squares (red and blue) enclose the spaxels used for the 3 × 3 correction or for the 5 × 5 correction. Top: AFGL 3116, blue camera of PACS (ObsID: 1342212512): well pointed and semi-extended source; PSFLC-3 × 3 correction has been applied. Center: same as above but for IRC−10529, red camera of PACS (ObsID: 1342208931): this is a mispointed observation where the blue spectrum corresponds to that extracted from the central spaxel without post-processing, while the red one is the spectrum taken from the brightest spaxel and with the post-processing applied (PSFLC-3 × 3). Bottom: same as the first two panels but for NGC 6543, red camera (ObsID: 1342238389): this is an extended source; PSFLC-5 × 5 correction applied.
