Integral Field Spectroscopy with Herschel PACS

Abstract

PACS (Poglitsch et al. [2]) was a photometer and integral field spectrograph (IFS) operating in the FIR (50–220 μm), aboard the ESA-NASA Herschel Space Observatory (Pilbrat et al. [1]). It was the first IFS ever on a space telescope. Herschel operated from May 2009 until April 2013, when its coolant ran out and after which it was sent off in a wide orbit around the sun. In this poster we discuss the importance of the spatial sampling of the PACS beam.
