TL;DR: The Photodetector Array Camera and Spectrometer (PACS) as discussed by the authors is one of the three science instruments on ESA's far infrared and sub-mil- limetre observatory.

TL;DR: In this article, the authors used the Spitzer Space Telescope and Herschel Space Observatory imaging of M31 to construct maps of dust surface density, dust-to-gas ratio, starlight heating intensity, and polycyclic aromatic hydrocarbon (PAH) abundance, out to R ≈ 25 kpc.

TL;DR: The PACS photometric system is very well characterized with a constant energy spectrum as discussed by the authors, and the PACS bolometer response was extremely stable over the entire Herschel mission and a single, time-independent response calibration file is sufficient for the processing and calibration of the science observations.

TL;DR: In this article, infrared to millimetre spectral energy distributions have been obtained for 41 bright ultra-luminous infrared galaxies with ISOPHOT between 10 and 200 micron and supplemented for 16 sources with SCUBA at 450 and 850 micron, and with SEST at 1.3 mm.

TL;DR: In this paper, a complete ISO view of PG quasars containing 64 infrared spectral energy distributions between 5 and 200 mu m was provided, where half of the sample was supplemented by MAMBO and SCUBA (sub-) millimeter data.
