The Great Observatories Origins Deep Survey (GOODS) aims to unite extremely deep observations from NASA's Great Observatories (Spitzer, Hubble and Chandra), ESA's Herschel and XMM-Newton, and the most powerful ground-based facilities. The aim is to survey the distant universe to the faintest flux limits across the broadest range of wavelengths.
Herschel HIFI Spectral Maps Highly Processed Data Products
Short Name:
HPDP
Date:

Publisher:
NASA/IPAC Infrared Science Archive
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.
All data for the Herschel SPIRE and PACS guaranted time program on Interstellar Medium (SAG-4) and other public data processed at IDOC. All data have been reprocessed at IDOC using advanded reprocessing pipeline.

Herschel Inventory of the Agents of Galaxy Evolution
Short Name:
HERITAGE

Description:
The HERschel Inventory of The Agents of Galaxy Evolution (HERITAGE) open time key program mapped the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) at 100, 160, 250, 350, and 500 microns using Herschel's PACS and SPIRE instruments. The overriding science goal of HERITAGE is to study the life cycle of matter as traced by dust in the LMC and SMC.
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 Multi-tiered Extragalactic Survey (HerMES) is a legacy programme (KPGT_soliver1) designed to map a set of nested fields totalling 380 sq. deg. Fields range in size from 0.01 to 20 sq. deg., using SPIRE at 250, 350 and 500 microns. These bands cover the peak of the redshifted thermal spectral energy distribution from interstellar dust and thus capture the reprocessed optical and ultraviolet radiation from star formation that has been absorbed by dust, and are critical for forming a complete multiwavelength understanding of galaxy formation and evolution.
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.
