From left to right: schematic view of the different FoVs involved in the analysis of SLW, SSW SPIRE, and PACS data. Left: in the SLW SPIRE map the green square highlights the FoV considered in the analysis (∼100″). These data are characterized by a beam of 35″ identified by the yellow small square. Middle: in the SSW SPIRE map the yellow square represents the 3 × 3 spaxels area involved in the analysis. The map is characterized by a beam of 19″ (small black square). Right: in the PACS map the black square identifies a FoV of ∼19″ (i.e., one SSW SPIRE spaxel) while the yellow square identifies a FoV of ∼35″. The star symbols represent those spaxels where the ¹²CO emission is observed: in particular, white stars highlight the spaxels characterized by stronger ¹²CO emission than that observed in the remaining spaxels marked using yellow stars. PACS data are characterized by a beam of 9.4″.
