All Herschel observations are processed through an automatic pipeline, which corrects a number of instrumental artifacts. The Highly Processed Data Products (HPDP) have gone through additional interactive processing, and represent an improvement over the standard products. HPDP from Herschel's Photoconductor Array Camera and Spectrometer (PACS) are available for JScanam maps, Unimap maps, and Red Leak Spectra.
During the years 2004 to 2017, the Palomar 60 inch telescope (P60) operated as a fully robotic facility to obtain targeted optical observations of gamma-ray burst (GRB) afterglows and other transient events. An automated pipeline reduced the data in real time. The raw, calibration, and pipeline-processed data are available here.

The Spitzer Science Center and IRSA have released a set of Enhanced Imaging Products (SEIP) from the Spitzer Heritage Archive. These include Super Mosaics (combining data from multiple programs where appropriate) and a Source List of photometry for compact sources. The primary requirement on the Source List is very high reliability -- with areal coverage, completeness, and limiting depth being secondary considerations. The SEIP include data from the four channels of IRAC (3.6, 4.5, 5.8, 8 microns) and the 24 micron channel of MIPS. The full set of products for the Spitzer cryogenic mission includes around 42 million sources.
The Spitzer Infrared Nearby Galaxy Survey is a comprehensive infrared imaging and spectroscopic survey of 75 nearby galaxies. Its primary goal is to characterize the infrared emission of galaxies and their principal infrared-emitting components, across a broad range of galaxy properties and star formation environments. SINGS provides new insights into the physical processes connecting star formation to the interstellar medium properties of galaxies and provides a vital foundation for understanding infrared observations of the distant universe and ultraluminous and active galaxies.
Level 1 / Basic Calibration Data (BCD) from Spitzer Space Telescope. BCDs are the individual data frames that emerge [calibrated] from the Spitzer pipeline.
Level 2 or post Basic Calibrated Data (PBCD) from Spitzer Space Telescope. This products come from combining the individual data frames or BCDs [such as mosaics of individual pointings].
LVL consists of a sample of 258 galaxies, which have been mapped with both IRAC (4 bands) and MIPS (3 bands). In addition, ancillary data products consisting of images in the narrow-band H-alpha line emission and broad-band R (from the ground) and the UV continuum (2 bands) from GALEX are also available for many of the galaxies.
This data set includes images of the galaxy cluster Abell 1763 at visible and infrared wavelengths: r', J, H, and Ks obtained using the Palomar 200in telescope, as well as the IRAC and MIPS images from Spitzer. The cluster is covered out to approximately 3 virial radii with deep 24 mum imaging (a 5sigma depth of 0.2 mJy). This same field of ~40' × 40' is covered in all four IRAC bands as well as the longer wavelength MIPS bands (70 and 160 mum). The r' imaging covers ~0.8 deg2 down to 25.5 mag, and overlaps with most of the MIPS field of view. The J, H, and Ks images cover the cluster core and roughly half of the filament galaxies, which extend toward the neighboring cluster, Abell 1770.
The Spitzer Survey of Stellar Structure in Galaxies (S4G) is a volume-, magnitude-, and size-limited survey of over 2300 nearby galaxies at 3.6 and 4.5μm. This is an extremely deep survey reaching an unprecedented 1σ surface brightness limit of μ3.6μm(AB) = 27 mag arcsec-2. This translates to a stellar surface density of << 1 M⊙ pc-2 ! S4G can thus probe the stellar structure in galaxies in a regime where the gas dominates the stars (typical HI surface density ~ a few M⊙ pc-2).
