Herschel
The European Space Agency's Herschel Space Observatory flew the largest single mirror (3.5-m in diameter) ever built for a space telescope. Herschel covered the spectral range from the far-infrared to submillimeter. This Space Observatory comprised three instruments :
- The Photodetector Array Camera and Spectrometer (PACS) instrument
- The Spectral and Photometric Imaging REceiver (SPIRE) instrument
- The Heterodyne Instrument for the Far Infrared (HIFI) instrument
The photometric bands are centered at 70, 100 and 160 microns for PACS, and at 250, 350 and 500 microns for SPIRE, with an angular resolution going from 5 arcsec to 37 arcsec.
CADE serves SPIRE and PACS photometric data for each Key-Programs. Healpix maps have all been smoothed to 37 arcsec. We also provide Healpix maps of the SPIRE data at 1 and 4 arcmin angular resolutions.
Concerning the PACS data, CADE serves Healpix maps of the Users Provided Data Products (UPDP) when available, or Highly Processed Data Products (HPDP). When none of these data were available, we produced healpix maps using data processed by the Herschel Pipeline (level 2.5 when possible) using:
- the High-Pass Filter (HPF) method denoted as HPFMAP
- the JScanam map maker denoted as JSMAP
- the Unimap map maker denoted as UNIMAP
The units of the Healpix maps are MJy/sr.
