Description
The PACS is one of three science instruments for ESA's Herschel Space Observatory (HSO, formerly known as FIRST). It operates either as an imaging photometer or an integral field spectrometer over the spectral band from 57 to 210 µm.
Technical Data
Imaging Capabilities:
Simultaneous two-band (same field of view) 60-85 µm or 85-130 µm and 130-210 µm imaging
Two filled bolometer arrays: 32x16 and 64x32 pixels
Point source sensitivity: ~3 mJy (5-sigma limit in 1 hour)
Spectroscopy Capabilities:
Simultaneous 57-105 µm and 105-210 µm spectroscopy
47"x47" (5x5 pixels) field-of-view rearranged via an image slicer on two 16x25 Ge:Ga detector arrays
Sensitivity: ~5x10^-18 W/m^2 (5-sigma in 1 hour)
