Abstract:
    This catalogue of known  Galactic  supernova  remnants  (SNRs)  is  an
    updated version of the catalogues of Galactic SNRs presented in detail
    in  Green (1984, 1988), in summary form  in Green (1991, 1996), and on
    the World-Wide-Web (versions of July 1995 and August 1996). (Note that
    version published in Green (1996) was produced in 1993.)

    This  September 1998 version of the catalogue contains 220 SNRs, which
    is  5 more than listed in the previous version. The basic summary data
    included  in this catalogue for each SNR are its Galactic coordinates,
    RA  and Dec (B1950.0), angular size (in arcmin), type, flux density at
    1 GHz, spectral index, and any other names. Notes on these parameters,
    on possible remnants not included, and questionable SNRs listed in the
    catalogue   are  given  in  full  version  of  the  catalogue  on  the
    World-Wide-Web.  It should be  noted that there  are serious selection
    effects  which apply to the identification of Galactic SNRs (see Green
    1991), so  that great care should  be taken if these  data are used in
    statistical studies.
