NASA/IPAC Infrared Science Archive
Description:
The high sensitivity and angular resolution of the 2MASS Large Galaxy Atlas (LGA) images allows closer inspection of diverse stellar populations, large-scale structures such as spirals, bulges, warps and bars, star formation regions and evolution of galaxies. This image atlas represents the first uniform, all-sky, view of galaxies as seen in the near-infrared wavelength window that is most sensitive to the dominant mass component of galaxies.

MAST Spectral Classes of Like Stars

Publisher:
Space Telescope Science Institute Archive
Description:
This table was created by cross correlating entries from the MAST "Table of Representative Spectra" with targets listed in the Skiff Spectral catalog, the Sky2000 catalog, and/or provided by Simbad. Spectra from IUE, STIS, FUSE, EUVE, HUT, GHRS, FOS, WUPPE, BEFS, and TUES are included. Most correlations were based on cross-matching target names and coordinates, usually with a 5" tolerance, but a few matches may be wrong. The table lists roughly 28,000 observations including novae and supernovae of which more than 22,000 have assigned spectral types.
305. MAXI Master Catalog

Title:
MAXI Master Catalog
Short Name:
MAXIMASTER
Date:
07 Mar 2025
Publisher:
NASA/GSFC HEASARC
Description:
The MAXIMASTER database table records high-level information of the Monitor of All-sky X-ray Image (MAXI) observations and provides access to the data archive. MAXI is a Japanese experiment located at the International Space Station (ISS), designed to continuously monitor, through a systematic survey, X-ray sources as the ISS orbits Earth. MAXI was launched by the space shuttle Endeavour on 2009 July 16, then mounted on port No. 1 on JEM-EF on July 24. After the electric power was turned on, MAXI started nominal observations on 2009 August 3. The MAXI data are a copy of the MAXI data processing; the output of which is hosted at the DARTS archive located at ISAS (<a href="https://darts.isas.jaxa.jp/astro/maxi/">https://darts.isas.jaxa.jp/astro/maxi/</a>). This catalog is then generated at the HEASARC by collecting high-level information from the data and is updated regularly during operation. This is a service provided by NASA HEASARC .
306. Mellinger All Sky Mosaic: Red

Title:
Mellinger All Sky Mosaic: Red
Short Name:
MELLINGER
Date:

Publisher:
NASA/GSFC HEASARC
Description:
This all sky mosaic was created by Axel Mellinger and is used in <i>SkyView</i> with his permission. A fuller description is available at the <a href="https://www.milkywaysky.com/">survey website</a>. <p> Between October 2007 and August 2009 a digital all-sky mosaic was assembled from more than 3000 individual CCD frames. Using an SBIG STL-11000 camera, 70 fields (each covering 40x27 degrees) were imaged from dark-sky locations in South Africa, Texas and Michigan. In order to increase the dynamic range beyond the 16 bits of the camera's analog-to-digital converter (of which approximately 12 bits provide data above the noise leve) three different exposure times (240s, 15s and 0.5 s) were used. Five frames were taken for each exposure time and filter setting. The frames were photometrically calibrated using standard catalog stars and sky background data from the Pioneer 10 and 11 space probes. the panorama has an image scale of 36"/pixel and a limiting magnitude of approximately 14. The survey has an 18 bit dynamic range. <p> The processing of these data used a custom data pipeline built using IRAF, Source Extractor and SWarp. <p> The data used here were converted to three independent RGB color planes of 8 bits each and provided to SkyView as a single 36000x18000x3 Cartesian projection cube. To allow users to efficiently sample data in a region of the sky, this cube was broken up into 2100x2100 pixel regions with a 50 pixel overlap between adjacent images. Tiles at the poles were 2100x2050. <p> In <i>SkyView</i> each color plane comprises a survey. The individual planes may be sampled as surveys independently as Mellinger-R, Mellinger-G and Mellinger-B. The color mosaics can be regenerated by creating an RGB image of all three surveys. Since <i>SkyView</i> may stretch the intensity values within each color, linear scaling and a minimum of 0 and maximum of 255 should be specified to keep the original intensity scalings. <p> The full spatial resolution data is used for images of less than 30 degrees on a side. If a user requests a larger region, data are sampled from a lower resolution 3600x1800x3 data cube. Please contact the survey author if you need to use the higher resolution data for larger regions. The Mellinger survey is only available in <i>SkyView</i> through the website. SkyView-in-a-Jar cannot access the underlying data. Provenance: Axel Mellinger. This is a service of NASA HEASARC.

Description:
The 4850MHz data is a combination of data from three different surveys: Parkes-MIT-NRAO (PMN) Southern (-88&amp;#176;; to -37&amp;#176;; declination) and tropical surveys (-29&amp;#176;; to -9&amp;#176;; declination, and (86+87) Green Bank survey (0&amp;#176;; to +75&amp;#176;; declination). The data contains gaps between -27&amp;#176;; to -39&amp;#176;;, -9&amp;#176;; to 0&amp;#176;;, and +77&amp;#176;; to +90&amp;#176;; declination. The 4850MHz survey data were obtained by tape from J.J. Condon and are comprised of 576 images and are used by permission. Full information pertaining to these surveys are found in the references.<P> Provenance: NRAO, generated by J.J. Condon, J.J. Broderick and G.A. Seielstad, Douglas, K., and Gregory, P.C..
