- Description:
- The GALEX Atlas of Nearby Galaxies contains images of 1034 nearby galaxies recently observed by the GALEX satellite in its far-ultraviolet (FUV; 1516A) and near-ultraviolet (NUV; 2267A) bands. The Atlas was prepared by A. Gil de Paz,S. Boissier, B.F. Madore, M. Seibert and associated members of the GALEX Team. The full paper is posted on astroph/0606440 and will be published in ApJS in 2007.

- GLEAM 72-103: GaLactic and Extragalactic Allsky MWA Survey
- Short Name:
- GLEAM1
- Date:

- 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.. This is a service of NASA HEASARC.

- GMRT 150 MHz All-sky Radio Survey: First Alternative Data Release
- Short Name:
- TGSS
- Date:
- 07 Mar 2025
- 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. The measured overall astrometric accuracy is better than 2" in RA and DEC, while the flux density accuracy is estimated at ~10 percent. Data is stored as 5336 mosaic images (5 deg x 5 deg). <p> <i>SkyView</i> uses Lanczos resampling and Sqrt image scaling by default for this survey. Provenance: TGS ADR Team.
