The Sydney University Molonglo Sky Survey (SUMSS) is a deep radio
survey at 843 MHz of the entire sky south of declination -30°;, made using
the Molonglo Observatory Synthesis Telescope (<a href="https://www.physics.usyd.edu.au/astrop/most/"> MOST </a>), located near Canberra, Australia.
The images from the SUMSS are produced as 4 x 4 degree mosaics of up to
seventeen individual observations, to ensure even sensitivity across
the sky. The mosaics slightly overlap each other. Data were last updated on January 28, 2015.
<p>
Images can also be obtained from the <a href="https://www.astrop.physics.usyd.edu.au/cgi-bin/postage.pl">SUMSS Postage Stamp Server</a>.
<p>
The SUMSS is intended to complement the NRAO-VLA Sky Survey (NVSS) which
covered the sky between +90 and -40 deg declination, at a
frequency of 1400MHz.

The Tartarus database contains the results of a detailed but systematic analysis of ASCA observations of active galactic nuclei (AGN). It contains source and background events files, spectra, ancillary response files and response matrices, images, and assorted light curves for a large number of ASCA AGN observations. Spectral fit results are done by automatic XSPEC fitting. This database table allows easy access to reduced AGN data for the whole community, allowing the maximum scientific return from the data. Availability of publishable light curves, images, and spectra (which can also be readily re-fitted) should be particularly valuable to astronomers with little direct experience in the reduction of X-ray data. Version 3.1 has been created by analyzing all ASCA observing sequences with targets designated as AGN, as indicated by a leading "7" in the ASCA observing sequence number. Version 3.1 contains products for all 611 observing sequences designated as AGN observations. This is a significant improvement over Versions 1 and 2. Moreover, the 611 sequences for which products are available are complete in the sense that either the target object was not detected (in which case an upper limit on GIS2 source counts is given) or the intended AGN target was detected and the data were fully analyzed. In order to obtain the most accurate background subtraction and minimize contamination from any nearby sources, version 3.1 makes more use of custom extraction regions than previous versions. It is expected that version 3.1 will be replaced when the final ASCA calibration is completed. This database table has been created by the Tartarus Team, and they, rather than Imperial College London or the HEASARC, are responsible for the contents. It was ingested by the HEASARC in August, 2005. This is a service provided by NASA HEASARC .
Taurus 2: Finishing the Spitzer Map of the Taurus Molecular Clouds
Short Name:
Taurus
Date:
27 Oct 2022 19:00:00
Publisher:
NASA/IPAC Infrared Science Archive
Description:
The Taurus Spitzer Legacy project has mapped ≈44 square degrees of the Taurus star-formation region using the IRAC and MIPS cameras aboard the Spitzer Space Telescope.
The AKARI Far-Infrared All-Sky Survey Maps cover >99% of the sky in four photometric bands centered at 65, 90, 140, and 160 microns, with spatial resolutions of 1'-1.5'.
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 Hawaii-HDF-N is an intensive multi-color imaging survey of 0.2 sq.
degrees centered on the HDF-N. Data were collected on the NOAO 4m Mayall telescope,
the National Astronomical Observatory of Japan 8.2m Subaru telescope and the
University of Hawaii 2.2m telescope.
Deep U, B, V, R, I, and z' data were obtained over the whole field and deep HK' data over
the Chandra Deep Field North. Details are available in the references.

Two different images are given in the V band (V0201 and V0401) from observations
separated by about a month that had substantial differences in seeing. Provenance: Data downloaded from the reference website. A formatting
error in the FITS files was corrected.. This is a service of NASA HEASARC.
The HI 4-PI Survey (HI4PI) is a 21-cm all-sky survey of neutral atomic
hydrogen. It is constructed from the Effelsberg-Bonn HI Survey (EBHIS), made
with the 100-m radio telescope at Effelsberg/Germany, and the Galactic All-Sky
Survey (GASS), observed with the Parkes 64-m dish in Australia. HI4PI
comprises HI line emission from the Milky Way. This dataset is the atomic
neutral hydrogen (HI) column density map derived from HI4PI
(|Vlsr| < 600 km/s). Provenance: Argelander-Institut für Astronomie (AIfA), Max-Planck-Institut für
Radioastronomie (MPIfR), and CSIRO/Australia; data provided by B. Winkel. This is a service of NASA HEASARC.
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 Galaxy Atlas (IGA) is a high resolution image atlas of the Galactic plane at 60 and 100 microns, it has been produced using the IRAS satellite data. The HIRES program was developed by the Infrared Processing and Analysis Center (IPAC) to produce high resolution (~ 1 arcmin) images from IRAS data using the Maximum Correlation Method (H.H. Aumann, J.W. Fowler and M. Melnyk, 1990, Astronomical Journal, 99, 1674).
