- Description:
- Roger et al. (1999) presented a map of the 22 MHz radio emission between declinations -28° and +80°, covering ~73% of the sky, derived from observations with the 22 MHz radiotelescope of the Dominion Radio Astrophysical Observatory (DRAO). The resolution of the telescope (EW x NS) is 1.2° x 1.7° secant(zenith angle). Roger et al. emphasize that the main value of the data lies in the representation of structure larger than the beam. The strongest point sources (Cas A, Cyg A, Tau A and Vir A) have been removed from the map. <p> The Centre d'Analyse de Données Etendues group used the data to form an all-sky HEALPix format map following the method described in Appendix A of Paradis et al. 2012, A&A, 543, 103, ADS. Their HEALPix map is mirrored here. The map is in units of K brightness temperature. Map pixels are set to a sentinel value of -32768.0 for unobserved regions and for regions affected by sidelobes around Cyg A, Tau A, and Vir A. Provenance: DRAO, MPI for Radio Astronomie.

- Description:
- 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.

- Description:
- This survey sums all data observed by the Fermi mission up to week 396. This version of the Fermi survey are intensity maps where the summed counts data are divided by the exposure for each pixel (in cm^2 s) and the area of the pixel. Data is broken into 5 energy bands <ul> <li> 30-100 MeV Band 1 </li> <li> 100-300 MeV Band 2 </li> <li> 300-1000 MeV Band 3 </li> <li> 1-3 GeV Band 4 </li> <li> 3-300 GeV Band 5 </li> </ul> The SkyView data are based upon a Cartesian projection of the counts divided by the exposure maps. In the Cartesian projection pixels near the pole have a much smaller area than pixels on the equator, so these pixels have smaller integrated flux. When creating large scale images in other projections users may wish to make sure to compensate for this effect the flux conserving clip-resampling option.

- Publisher:
- NASA/IPAC Infrared Science Archive
- Description:
- The Formation and Evolution of Planetary Systems (FEPS) Spitzer Legacy program was designed to characterize the evolution of circumstellar gas and dust around solar-type stars between ages of 3 Myr and 3 Gyr. To achieve these goals, FEPS obtained spectrophotometric observations with the Spitzer Space Telescope for a sample of 328 stars. The observing strategy was to measure the spectral energy distribution (SED) between wavelengths of 3.6 and 70 μm with IRAC and MIPS photometry, and between 8 and 35 μm with low-resolution IRS spectra. In addition, the FEPS program obtained MIPS 160 μm photometry for 80 stars to search for colder dust, and high-resolution IRS spectra for 33 sources to probe for circumstellar gas.

- Description:
- The GALEX, Galaxy Explorer, mission was launched by a Pegasus-XL vehicle on April 28 2003 into a 690km altitude, 29 degree inclination, circular orbit with a 98.6 minute period. The GALEX instrument allows imaging and spectroscopic observations to be made in two ultraviolet bands, Far UV (FUV) 1350-1780A and Near UV (NUV) 1770-2730A. The instrument provides simultaneous co-aligned FUV and NUV images with spatial resolution 4.3 and 5.3 arcseconds respectively. Details of the performance of the instrument and detectors can be found in Morrissey et al. (2007) ApJS, 173, 682. <p> The <i>SkyView</i> GALEX surveys mosaic the intensity images of All-Sky Survey images. For a given pixel only the nearest image is used. Since a given GALEX observation is circular, this maximizes the coverage compared with default image finding algorithms which use the distance from edge of the image. <p> As of February 10, 2011, SkyView uses the GALEX GR6 data release.

- Short Name:

- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- GLEAM, the GaLactic and Extragalactic All-sky MWA survey, is a survey of the entire radio sky south of declination 30 degrees at frequencies between 72 and 231 MHz. It was made with the Murchison Widefield Array (MWA) using a drift scan method that makes efficient use of the MWA's very large field-of-view. The survey is described in Wayth et al. (2015) and the <a href="https://www.mwatelescope.org/gleam">website</a> at https://www.mwatelescope.org/gleam. <p> The data presented here are from the first year of GLEAM observing, published in: <ul> <li> Hurley-Walker et al. (2017): 25,000 square degrees of extragalactic sky <li> For et al. (2018): the Large and Small Magellanic Clouds <li> Hurley-Walker et al. (2019c): 8,000 square degrees of the Galactic plane </ul> A region around Centaurus A, a few other small regions described by Hurley-Walker et al. (2017), and the Galactic plane between 180 < l < 345 degrees, are not available. <p> The most sensitive and highest-resolution image is the 170-231MHz image which was used for all source-finding in generating the catalogue. It has a resolution of approximately 2.2 x 2.2/cos (dec + 26.7) arcmin at this frequency. However, due to ionospheric distortions, the final resolution of the survey varies by ~10% over the sky, with a direction-dependent PSF. <p> The <i>SkyView</i> data for the GLEAM surveys was extracted using the team's cutout server, into small (3 degree) raw cutouts over the region covered by the GLEAM survey. These cutouts have somewhat variable size and resolution. The default scale (i.e., pixel size) used for <i>SkyView</i> images is given in the table below. Since the GLEAM cutout server will not create an appropriately sized tile for the Sourth Pole, a larger tile offset from the pole is used. <p> <i>SkyView</i> resamples the cutouts retreived from the GLEAM website into the image geometry requested by the user. Only four wide-band datasets are included. The table below gives the frequency range, central frequency and a typical pixel scale for each of these bands. <table border> <tr><th colspan=5> GLEAM Bands In <i>SkyView</i> </th></tr> <tr><th>Band</th> <th>f<sub>min</sub> (MHz)</th> <th>f<sub>max</sub> (MHz)</th> <th>f<sub>C</sub> (MHz)</tg> <th>Pixel scale (") </th> </tr> <tr> <td> 1 </td><td> 72 </td><td>103 </td><td> 88 </td> <td> 56 </td></tr> <tr> <td> 2 </td><td>103 </td><td>134 </td><td>118 </td> <td> 44 </td></tr> <tr> <td> 3 </td><td>138 </td><td>170 </td><td>155 </td> <td> 34 </td></tr> <tr> <td> 4 </td><td>170 </td><td>231 </td><td>200 </td> <td> 28 </td></tr> </table> These data and 20 narrower bands are available through the team website. <p> To minimize resampling artifacts, this survey defaults to the Lanczos third order resampler. SkyView tracks the size and orientation of the beam as given in each of the tiles and includes the averaged value (i.e., the average of the input images weighted by the output pixels sampled from each input) in the BMAJ, BMIN, and BPA keywords of any result FITS file. Provenance: Source data extracted as cutouts from <a href="http://gleam-vo.icrar.org/gleam_postage/q/form">GLEAM cutout server</a> in March 2020 with updates in July 2020..

- GMRT 150 MHz All-sky Radio Survey: First Alternative Data Release
- Short Name:
- TGSS
- Date:
- 10 May 2024
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The first full release of a survey of the 150 MHz radio sky observed with the Giant Metrewave Radio Telescope between April 2010 and March 2012 as part of the TGSS project. Aimed at producing a reliable compact source survey, the automated data reduction pipeline efficiently processed more than 2000 hours of observations with minimal human interaction. Through application of innovative techniques such as image-based flagging, direction-dependent calibration of ionospheric phase errors, correcting for systematic offsets in antenna pointing, and improving the primary beam model, good quality images were created for over 95 percent of the 5336 pointings. This data release covers 36,900 square degrees (or 3.6 pi steradians) of the sky between -53 deg and +90 deg DEC, which is 90 percent of the total sky. The majority of pointing images have a background RMS noise below 5 mJy/beam with an approximate resolution of 25" x 25" (or 25" x 25" / cos (DEC - 19 deg) for pointings south of 19 deg DEC). The associated catalog has 640 thousand radio sources derived from an initial, high reliability source extraction at the 7 sigma level.

- Description:
- The GOODS NICMOS Survey (GNS) is a 180 orbit Hubble Space Telescope survey consisting of 60 pointings with the NICMOS-3 near-infrared camera. Each pointing is centred on a massive galaxy (M<sub>*</sub> > 1011 M<sub>sun</sub>) in the redshift range 1.7 < z < 3, selected by their optical-to-infrared colours (Papovich+06,Yan+04,Daddi+07) from the GOODS (Great Observatories Origins Deep Survey) fields. <p> The positions of the 60 GNS pointings were optimised to contain as many massive galaxies as possible and are partly overlapping, covering a total area of about 45 arcmin2. The field of view of the NICMOS-3 camera is 51.2 × 51.2 arcsec with a resolution of about 0.1 arcsec/pixel. The PSF has a width of about 0.3 arcsec FWHM. The limiting magnitude in H band reached at 5σ is HAB = 26.8, about 2 magnitudes fainter than in available ground based data of the GOODS fields.

- NASA/GSFC HEASARC
- Description:
- The Soviet orbital observatory GRANAT was launched in December 1989 and was operational till November 1998. One of the main instruments of the observatory was the French-Soviet hard X-ray coded mask telescope SIGMA (Paul et al.1 1991, Adv.Space Res., 11, 279). It was the first space telescope that used coded aperture technique for reconstruction of sky images in hard X-rays (35-1300 keV). The angular resolution of the telescope was approximately 12' and the accuracy of a source localization is approximately 2-3'.<p> SIGMA discovered numerous interesting hard X-ray sources including GRS 1758-258, which is located only 40' from bright soft X-ray source GX 5-1. It detected hard X-ray flux from X-ray burster A1742-294, which is very near to bright black hole binary 1E1740.7-2942. SIGMA set an upper limit on the hard X-ray flux of from the central supermassive black hole in our Galaxy.<p> During the period 1990-1998 SIGMA observed more that one quarter of the sky with sensitivity better than 100 mCrab. The Galactic Center region had the deepest exposure ( approximately 9 million sec), with the sensitivity to a source discovery (S/N > ~ 5) or approximately 10 mCrab.<p> A list of all detected sources with references to publications on them is presented in the paper of Revnivtsev et al. 2004, Astr. Lett. v.6. In these survey images (40-100 keV) all performed observations are averaged together. Transient sources that were discovered by SIGMA may not visible in the averaged image. <p> This survey has some features that users should keep in mind. The SIGMA telescope is a complicated instrument and is strongly dominated by the accuracy of the background subtraction. The presence of a very bright source in the field of view of the telescope sometimes cannot be fully accounted for and as a result of it some 'ghost' sources can appear. Such features can be seen in the regions near very bright sources like Crab Nebula, Cyg X-1, Nova Per 1992, Nova Mus 1991, Nova Oph 1993, and in the Galactic Center region. In addition to its nominal field of view (~17x17 deg) located around the optical axis of the telescope, SIGMA had another window of relatively high transparency of its shield, approximately 20-30&#176;; apart from the optical axis. Becuase of this a very bright sources like Cyg X-1 can cause non zero illumination of the SIGMA detector if they are located approximately 20-30&#176;; from the optical axis. The ring-like features caused by this effect, can be seen around Cyg X-1, and Nova Per 1992. <p> The count rate of detected sources (or upper limits) can be roughly translated into mCrab using the fact that that Crab nebula gives the count rate approximately 2.8e<sup>-3</sup> cnts/s in the units, provided in 'flux' maps Provenance: High Energy Astrophysics Department, Space Research Institute, Moscow, Russia; CEA, Centre d'Etudes de Saclay Orme des Merisiers, France; Centre d'Etude Spatiale des Rayonnements, Toulouse, France; F&eacute;d&eacute;ration de Recherche Astroparticule et Cosmologie Universit&eacute; de Paris, France.
