Abstract

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.  Provenance:  All data is downloaded from the <a href="https://galex.stsci.edu">
       MAST GALEX archive</a>.. This is a service of NASA HEASARC.
