The Online Digitized Sky Surveys (DSS1 & 2) server at the ESO/ST-ECF Archive provides access to the CD-ROM set produced by the Space Telescope Science Institute through its Guide Star Survey group. The images of these surveys are based on photographic data obtained using the Oschin Schmidt Telescope on Palomar Mountain and the UK Schmidt Telescope. The plates were processed into the present compressed digital form with the permission of these institutions. The photographic plates were scanned to a pixel scale of about 1.7 arcseconds per pixel for the POSS, SERC, and Palomar Quick-V surveys, and to about 1.0 arcseconds per pixel for the POSS-II surveys. Images of any part of the sky may be extracted from the DSS, in either FITS or GIF format.
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.

The high sensitivity and angular resolution of the 2MASS Large Galaxy Atlas (LGA) images allows closer inspection of diverse stellar populations, large-scale structures such as spirals, bulges, warps and bars, star formation regions and evolution of galaxies. This image atlas represents the first uniform, all-sky, view of galaxies as seen in the near-infrared wavelength window that is most sensitive to the dominant mass component of galaxies.
These Lockman Hole (LH) data represent a preliminary analysis of the deep 2MASS observations of this region, and are not a product endorsed by the 2MASS project. These data are described in The Astronomical Journal, Volume 125, Issue 5, pp. 2521-2530 "A Deep 2MASS survey of the Lockman Hole" by Beichman et al.
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.
The Extended IRAS Galaxy Atlas (EIGA) is an extension of the original IRAS Galaxy Atlas (IGA) to b = 6.7 deg.. High resolution images at 60 microns and 100 microns have been produced to match the latitude coverage of radio continuum observations obtained as part of the Canadian Galactic Plane Survey (CGPS). Also associated with the EIGA and IGA is the Mid-Infrared Galaxy Atlas (MIGA).
The Infrared Telescope in Space (IRTS) is a cryogenically cooled, small infrared telescope that flew from March - April in 1995. It surveyed approximately 10% of the sky with a relatively wide beam during its 20 day mission.
Four focal-plane instruments , the Near-Infrared Spectrometer (NIRS), the Mid-Infrared Spectrometer (MIRS), the Far-Infrared Line Mapper (FILM), and the Far-Infrared Photometer (FIRP) made simultaneous observations of the sky at wavelengths ranging from 1 to 1000 um.
The IRAS Sky Survey Atlas (ISSA) is a survey of 98% of the sky in four bands with effective wavelengths of 12, 25, 60 and 100 microns, which was done during a ten month period from January to November, 1983. The ISSA covers the sky with 430 fields. Each field is a 12.5 deg. by 12.5 deg. region centered every 10 deg. along declination bands which are spaced 10 deg. apart.
The Midcourse Space Experiment (MSX), a Ballistic Missile Defense Organization satellite, was launched in April 1996. The first ten months of the mission were devoted to mid-infrared observations with a solid hydrogen-cooled telescope. This instrument had five line-scanned focal plane arrays that spanned the spectral region from 4.2 to 26 microns.
