Description:
The 6dF Galaxy Survey (6dFGS) aims to measure the redshifts of around 150 000 galaxies, and the peculiar velocities of a 15 000-member subsample, over almost the entire southern sky. The table called Spectra contains the redshifts and qualities of all the observations. When complete, it will be the largest redshift survey of the nearby Universe, reaching out to about z ~ 0.15, and more than an order of magnitude larger than any peculiar velocity survey to date. The targets are all galaxies brighter than K tot = 12.75 in the 2MASS Extended Source Catalog (XSC), supplemented by 2MASS and SuperCOSMOS galaxies that complete the sample to limits of (H, J , r F, bJ) = (13.05, 13.75, 15.6, 16.75). This is the Data Release 3 version.
The Digitized Sky Survey (DSS) is a ground-based imaging survey of the entire sky in several colors. The survey, performed with Palomar and UK Schmidt telescopes, produced photographic plates that were later digitized at the Space Telescope Science Institute (STScI) to produce the Hubble Guide Stars Catalog (GSC).
Each plate produced by the Survey covers 6.5 x 6.5 degrees of the sky, and the plates have been digitized using a modified PDS microdensitometer. The digital images have a pixel size of either 25 microns (1.7 arcsec per pixel) or 15 microns (1.0 arcsec per pixel), and are 14000 x 14000 or 23040 x 23040 pixels per side. The images are stored on 12-inch optical media and are difficult to access quickly.

The ERO program is an initiative of the Euclid Science Team / ESA to collect 1 day of observations to showcase the Euclid mission and its capabilities before the start of the nominal survey. The ERO data products available at IRSA for the convenience of the US astronomy community are the same data products that are available through ESAC. The FITS files were processed with an ERO-specific pipeline, which is different from the standard Euclid pipeline that will be used for future data releases.
The Eureka Lawrence Berkeley National Laboratory (LBNL) Far-IR Lockman Hole (ELFLock) maps are intended to measure the Far-IR background radiation with 160-micron observations from the Multiband Imaging Photometer for Spitzer (MIPS). The download gives the largest contiguous low-cirrus 160 micron far-infrared map made with Spitzer data, covering 8.5 square degrees. It also differs from standard Spitzer-processed mosaic maps in that the background information is preserved, where it is normally removed by median filtering (for point-source studies). The map is composed of BCD data from S16 processing of data sets with these Spitzer Astronomical Observation Requests (AORs). Its flux units are MJy/Sr and the pixel size is 15.9", though flux = 0.0 for pixels without data.
Far-Infrared Deep Extragalactic Legacy Survey (FIDEL) contains sensitive and extensive far-infrared deep field observations with Spitzer to detect warm dust emission from hundreds of relatively ordinary starburst galaxies and active galactic nuclei at redshifts of 1 to 2 (7 to 10 billion years ago), and thousands more nearby. The survey also detected tens of thousands of high redshift objects at mid-infrared wavelengths. The program obtained data in three fields on the sky. The bulk of the data is in two fields, the Extended Chandra Deep Field South (ECDFS) and the Extended Groth Strip (EGS). A smaller amount of additional data was obtained in the GOODS-North area.
The Galactic Legacy Infrared Midplane Survey Extraordinaire (GLIMPSE) program covered the Galactic plane with the Spitzer IRAC instrument. GLIMPSEI covered 220 sq. degrees at |l|=10d-65d and b=-1d - +1d. GLIMPSEII covered the Galactic Center, l=-10d - +10d. GLIMPSE3D added vertical extensions, typically to |b|<+3d. GLIMPSE360 covered the outer Galaxy (l=65d-265d) with IRAC 3.6 micron and 4.5 micron imaging. The Vela-Carina program covered l=255d-295d.
Herschel data from the 'Galactic Observations of Terahertz C' (GOT Cplus) Open Time Key Program (KPOT_wlanger_1) are available here using spatial and visualization tools. GOT Cplus surveyed the Galactic Plane in the 158 micron (1.9 THz) fine structure transition of [CII] using Herschel's HIFI instrument. GOT Cplus is a sparse survey containing 454 lines of sight throughout the Galactic Disk, plus two position-velocity maps across the Galactic center.

Description:
The Galaxy Evolution Explorer (GALEX) satellite is a NASA mission led by the California Institute of Technology to investigate how star formation in galaxies evolved from the early Universe up to the present. GALEX uses microchannel plate detectors to obtain direct images in the near-UV (NUV) and far-UV (FUV) and a grism to disperse light for low resolution spectroscopy
