Description:
The Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) is a survey of 600 deg^2 in five photometric bands - 100, 160, 250, 350 and 500 microns - with the Photoconductor Array Camera and Spectrometer (PACS) and Spectral and Photometric Imaging Receiver (SPIRE) cameras. H-ATLAS DR1 includes the survey of three fields on the celestial equator, covering a total area of 161.6 deg^2 and previously observed in the Galaxy and Mass Assembly (GAMA) spectroscopic survey.
The Herschel Gould Belt Survey is one of the largest Herschel Key Projects. It conducted extensive far-infrared and submillimeter mapping of nearby molecular clouds with both the SPIRE and PACS instruments. It covered the bulk of the nearest (d <= 0.5 kpc) cloud complexes in the Galaxy, which are mostly located in the Gould Belt, a giant (700 pc by 1000 pc), flat structure inclined by 20d to the Galactic plane.

Description:
Herschel's Heterodyne Instrument for the Far Infrared (HIFI) produced far-infrared spectral maps. HIFI data products automatically processed with the Standard Product Generation (SPG) pipeline are available through the Herschel Data Search. In contrast, the HIFI Highly Processed Data Products (HPDPs) available here have been produced by HIFI instrument scientists using the Herschel Interactive Processing Environment (HIPE), and can be regarded as being as close to science-ready as possible. HPDPs are available for observations taken in the On-The-Fly (OTF) and Dual Beam Switch (DBS) Raster modes during science programs and calibration campaigns, over the Routine and Check-Out phases. The first HPDP delivery (DR1, Nov. 2016) consists of Band 6 and 7 maps.
The Herschel High Level Images (HHLI) are a subset of the data in the Herschel Science Archive (HSA), the entire contents of which are accessible at IRSA through the Herschel Data Search tool. The HHLI represent PACS and SPIRE image products that have been processed to the highest level available through the Standard Product Generation (SPG) pipeline, version 14.0. They are provided here as a convenient way for users to quickly visualize PACS and SPIRE imaging for any given region on the sky observed by these two instruments.
Because the galaxies of the Local Group have such large angular sizes, much of their diffuse, large-angular-scale emission is filtered out by the Herschel data reduction process. This work restores this previously missed dust in Herschel observations of the Large Magellanic Cloud, Small Magellanic Cloud, M31, and M33 by combining Herschel data (including new reductions for the Magellanic Clouds), in Fourier space, with lower-resolution data from all-sky surveys (Planck, IRAS, and COBE) that did not miss the extended emission.
The Herschel Orion Protostar Survey (HOPS, KPOT_tmegeath_2) is a sample of 410 young stellar objects (YSOs) in the Orion molecular clouds, selected from Spitzer data. Most objects have near-infrared photometry from 2MASS, mid- and far-infrared data from Spitzer and Herschel, and submillimeter photometry from APEX; thus, the SEDs cover 1.2 - 870 microns and are used to classify the sample into protostellar classes. Of the 410 YSOs, 330 have Spitzer and Herschel data and are mostly protostars; the remaining objects include likely extragalactic contaminants and faint YSOs. Using mid-IR spectral indices and bolometric temperatures, the sample of 330 YSOs is classified into 92 Class 0 protostars, 125 Class I protostars, 102 flat-spectrum sources, and 11 Class II pre-main-sequence stars. HOPS also implements a simple protostellar model (including a disk in an infalling envelope with outflow cavities) to generate a grid of 30,400 model SEDs and uses it to determine the best-fit model parameters for each protostar.
HeViCS is a survey of about 55 sq deg of the nearby Virgo galaxy cluster, obtained with the Herschel Space Observatory using the instruments PACS and SPIRE in parallel mode. It provides a wavelength coverage in five bands from about 100 to 600 microns. The science goals include: a) The detection of dust in the intra-cluster medium, b) Extended cold dust around galaxies, c) FIR-submm luminosity functions, d) The UV to sub-mm spectral energy distribution of galaxies of various morphological types, e) The detection of dust in dwarf and giant elliptical galaxies.

The Canada-France-Hawaii Telescope Legacy Survey is a 5-year program carried out jointly by the Canadian and French agencies. It will use the Megaprime/Megacam instrument mounted at
prime focus of the 3.6m CFH telescope during the period 2003-2008. The Deep survey concerns 4 patchsof 1 square-degree. All will be observed in u,g,r,i and z, with very lon gexposure time<p>
