Description
The Photodetector Array Camera and Spectrometer (PACS) is one of the
three science instruments on ESA's far infrared and submillimetre
observatory. It employs two Ge:Ga photoconductor arrays (stressed and
unstressed) with 16×25 pixels, each, and two filled silicon
bolometer arrays with 16×32 and 32×64 pixels, respectively,
to perform integral-field spectroscopy and imaging photometry in the
60-210 μm wavelength regime. In photometry mode, it simultaneously
images two bands, 60-85 μm or 85-125 μm and 125-210 μm, over a
field of view of ~1.75'× 3.5', with close to Nyquist beam sampling
in each band. In spectroscopy mode, it images a field of 47”
× 47”, resolved into 5×5 pixels, with an instantaneous
spectral coverage of ~1500 km s-1 and a spectral resolution
of ~175 km s-1. We summarise the design of the instrument,
describe observing modes, calibration, and data analysis methods, and
present our current assessment of the in-orbit performance of the
instrument based on the performance verification tests. PACS is fully
operational, and the achieved performance is close to or better than the
pre-launch predictions.
Herschel is an ESA space observatory with science instruments provided
by European-led Principal Investigator consortia and with important
participation from NASA.
