VII/163    A Catalogue of Galactic Supernovae Remnants (Green 1994)

A Catalogue of Galactic Supernovae Remnants Green, D.A. <in Proc. IAU Colloq. 145, "Supernovae and Supernovae Remnants", held May 22-29 1993, in Xian, China, Eds. McCray, R., and Wang, Z., Camb. Univ. Press (1994)>
ADC_Keywords: Supernova remnants - 970 ; Milky Way - 395, Nonstellar objects - 430 Abstract: This catalog lists all galactic supernova remnants known and is an updated version of the catalogues of Galactic SNRs presented in detail in Green (1984, MN, 209, 449; 1988, ApSS, 148, 3) and in summary form in Green (1991, PASP, 103, 209). The basic parameters of the 182 SNRs included in this (1993 May) version of the catalogue are, for each SNR, 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 the documentation. 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.

Note on GLON, GLAT: Galactic Coordinates are the source centroid quoted to the nearest tenth of a degree. Note on RAh, RAm, RAs, DE-, DEd, DEm: The accuracy of the quoted values depends on the size of the remnant. For small remnants they are to the nearest few seconds of time and the nearest minute of arc for RA and DEC respectively. For the larger remnants they are rounded to coarser values. They are in every case sufficient to specify a point within the boundaries of the remnant. These coordinates are deduced from radio maps rather than from X-ray or optical observations, and are B1950.0. Note on F(1GHz): The flux density of the remnant at !GHz in Jansky. This is not a measured value, but that deduced from the observed radio frequency spectrum of the source. The frequency of 1GHz is chosen because flux density measurements at frequencies both above and below this value are usually available. Note on type: S remnant shows a shell F remnant shows a filled center C remnant shows a composite or combination radiostructure S?, C?, F? if there is some uncertainty ? object is conventionally considered a SNR although its nature is poorly known or not well understood.
