TheoSSA provides spectral energy distributions based on model
atmosphere calculations. Currently, we serve results obtained using
the Tübingen NLTE Model Atmosphere Package (TMAP) for hot compact
stars.
The Southern H-Alpha Sky Survey Atlas is the product of a wide-angle
digital imaging survey of the H-alpha emission from the warm ionized
interstellar gas of our Galaxy. This atlas covers the southern hemisphere
sky (declinations less than +15 degrees). The observations were taken with
a robotic camera operating at Cerro Tololo Inter-American Observatory (CTIO)
in Chile. The atlas consists of 2168 images covering 542 fields. There are four
images available for each field: <b>H-alpha</b>, <b>Continuum</b>, <b>Continuum-Corrected</b>
(the difference of the H-alpha and Continuum images), and <b>Smoothed</b> (median filtered to 5 pixel, or 4.0 arcminute, resolution to remove star residuals better). The <a href="https://amundsen.swarthmore.edu/SHASSA">SHASSA website</a> has more details of the data and the status of this and related projects. Images can also be
obtained from the <a href="https://amundsen.astro.swarthmore.edu/SHASSA/#Images">Download Images</a> section at the SHASSA site. Provenance: John E. Gaustad (Swarthmore College), Peter R. McCullough (University of Illinois), Wayne Rosing (Las Cumbres Observatory), and Dave Van Buren (Extrasolar Research Corporation). This is a service of NASA HEASARC.
The Spitzer Wide-area InfraRed Extragalactic Survey
Short Name:
SWIRE

Publisher:
NASA/IPAC Infrared Science Archive
Description:
* A wide-area, high galactic latitude imaging survey conducted using the Spitzer MIPS far-infrared and IRAC mid-infrared cameras. The satellite data will be complemented by an extensive program of ground-based optical, near-infrared and radio observations.
The VSOP (the VLBI Space Observatory Programme) 5 GHz AGN (Active Galactic Nuclei) Survey Program Analysis Data
Short Name:

Description:
A significant fraction of the mission time of VSOP was to be dedicated to the VSOP Survey Programme of bright compact Active Galactic Nuclei (AGN) at 5 GHz, which was lead by ISAS. The VSOP Survey Sources are an unbiased dataset of 294 targets, of which 82% were successfully observed.
The WiggleZ Project Data Archive.
The WiggleZ Dark Energy Survey is a survey of 240,000 emission-line galaxies measured with the AAOmega spectrograph of the 3.9-m Anglo-Australian Telescope (AAT). The aim of the survey is to measure the scale of baryon acoustic oscillations (BAO) imprinted on the spatial distribution of these galaxies. The survey will sample a volume of 1 Gpc3 over an area on the sky of 1000 square degrees with an average target density of 350 galaxies per square degree.
The survey commenced in August 2006 and was completed in January 2011.
z0MGS is an archival project combining WISE and GALEX images of nearby galaxies. The main sample consists of ~11,000 galaxies that are deemed to have >10% probability of being within D %lt; 50 Mpc and of having MB %lt; -18. In addition, in the course of iterating on distance estimates when creating the atlas, the z0MGS team generated images for ~5, 000 additional galaxies. These are also included in the delivery, although they do not meet the formal selection criteria. All galaxies included in the atlas have WISE W1 coverage, at minimum. In total, out of the 15,748 galaxies in DR1, 15,716 have coverage in all WISE bands, 11,687 have GALEX NUV and 10,754 have GALEX FUV. If you use z0MGS data, please cite Leroy et al. (2019)
The Archive is formed with all files measured with ARcetri Near Infrared CAmera ( ARNICA). Each files contains (in FITS format) or a single exposure or the mean of single exposures taken at the same telescope position. The filer used can be either a Johnson broad band infrared filter (J, H, K), or a narrow band filter (see ARNICA) page for details). Most measures was acquired at the TIRGO telescope, while a smaller sample cames from the few telescopes Arnica was ported to (WHT, NOT, VATT and TNG). All frame are in FITS format and are 256x256 pixels in size. The archive contains more than 250.000 frames. Most files belongs to a compound measure (we call them "a mosaic").

Description:
The Tübingen NLTE Model-Atmosphere Package (`TMAP
<http://astro.uni-tuebingen.de/%7ETMAP/TMAP.html>`_) is a tool to calculate
stellar atmospheres in spherical or plane-parallel geometry in hydrostatic
and radiative equilibrium allowing departures from local thermodynamic
equilibrium (LTE) for the population of atomic levels./TMAP/ is based on
the so-called Accelerated Lambda Iteration (ALI) method and is able to
account for line blanketing by metals. All elements from hydrogen to nickel
may be included in the calculation with model atoms which are tailored for
the aims of the user.
DOLORES (Device Optimized for the LOw RESolution) is a focal reducer instrument installed at the Nasmyth B focus of the TNG. The detector is a 2048 x 2048 E2V 4240 Thinned back-illuminated, deep-depleted, Astro-BB coated CCD with a pixel size of 13.5 µ. The scale is 0.252 arcsec/px which yields a field of view of about 8.6 x 8.6 arcmin. The instrument allows imaging through broad and narrow band filters as well as spectroscopic observations with resolving powers between RS=~500 and RS=~6000. A multi-slit mode, based on custom masks manufactured by a dedicate cutting machine, is also available. Please note that MOS programs are bound to strict constraints on the number of masks and on the time necessary to design and manufacture them. In particular, each program can request up to a maximum of 5 masks per night and 10 masks per observing run.
