Description:
This catalog of known Galactic supernova remnants (SNRs) is an updated version of the catalogs of Galactic SNRs presented in detail in Green (1984, 1988), in summary form in Green (1991, 1996, 2004, 2009), and on the Web (versions of 1995-July, 1996-August, 1998-September, 2000-August, 2001-December, 2004-January, 2006-April, 2009-March, and 2014-May). [Note that the version published in Green (1996) was produced in 1993.] This June 2017 version of the catalog contains 295 SNRs, and is based on results published in the literature up to the end of 2016. The basic summary data included in this catalog for each SNR are its designation, position, angular size (in arcminutes), type, flux density at 1 GHz, spectral index, and any other names by which it is known. Notes on these parameters, on possible remnants not included, and on questionable SNRs that are listed in this catalog, are given in the full version of the catalog on the Web at <a href="http://www.mrao.cam.ac.uk/surveys/snrs/snrs.info.html">http://www.mrao.cam.ac.uk/surveys/snrs/snrs.info.html</a> It should be noted that there are serious selection effects which apply to the identification of Galactic SNRs (e.g., Green 1991, 2004, 2005, 2009, 2014), so that care should be taken if these data are used in any statistical studies. This version of the Green Catalog of Galactic Supernova Remnants was ingested at the HEASARC in July 2017. It is based on the Catalogue of Galactic Supernova Remnants, 2017 June version, <a href="https://cdsarc.cds.unistra.fr/ftp/cats/VII/278">CDS Catalog VII/278</a>, file snrs.dat, obtained from the CDS at <a href="http://cdsarc.u-strasbg.fr/ftp/cats/VII/278/">http://cdsarc.u-strasbg.fr/ftp/cats/VII/278/</a>.
