MOSTSNRCAT - Molonglo Observatory Synthesis Telescope Supernova Remnant Catalog
The MOST supernova remnant catalogue (MSC). Whiteoak J.B.Z., Green A.J. <Astron. Astrophys. Suppl. Ser. 118, 329 (1996)> =1996A&AS..118..329W (SIMBAD/NED BibCode)
This status flag takes the following possible values:
k: Known SNR (Table MSC.A of the paper) n: New SNR (Table MSC.B of the paper) p: Possible SNR (Table MSC.C of the paper) r: Reclassifed (section 3.3 of the paper)
This parameter is set to 'Y' to indicate that a note exists for this SNR in the associated notes file ftp://cdsarc.u-strasbg.fr/pub/cats/J/A+AS/118/329/notes.dat
The name of the supernova remnant using the designation 'MSC LLL.l+B.b' (Most Supernova Catalog and the galactic coordinates of the SNR), as recommended by the CDS Dictionary of Nomenclature of Celestial Objects. In the original reference paper, the generic 'G' prefix was used instead of 'MSC '.
The Right Ascension of the position of the geometric center of the SNR in the selected equinox. When the object does not have a complete shell, the center and dimensions of the ring which best describes the remnant were used. The RA was given in J2000.0 coordinates to a precision of 1 second of time in the original table.
The Declination of the position of the geometric center of the SNR in the selected equinox. When the object does not have a complete shell, the center and dimensions of the ring which best describes the remnant were used. The Declination was given in J2000.0 coordinates to a precision of 1 arcminute in the original table, except for the possible SNR (objects with snr_status = 'p') where it was given to a precision of 1 arcsecond.
The Galactic Longitude of the SNR.
The Galactic Latitude of the SNR.
This parameter is set to '>' if the quoted integrated flux density of the SNR at 0.843 GHz is a lower limit (typically for large objects).
The integrated flux density of the SNR at 0.843 GHz, in mJy.
The major diameter of the SNR's shell or equivalent elliptical ring, at 0.843 GHz, in arcminutes.
The minor diameter of the SNR's shell or equivalent elliptical ring, at 0.843 GHz, in arcminutes.
This parameter is set to '>' if the quoted mean surface brightness of the SNR at 0.843 GHz is a lower limit (typically for large objects).
The mean surface brightness of the SNR at 0.843 GHz, in Jy/sr.
This parameter indicates the type of SNR:
S: shell P: plerion or filled-centre C: composite M: apparent multiple shell structure
The figure number in the reference paper in wich the SNR is depicted (not given for possible SNR, i.e., objects with snr_status='p').
A reference code for references to previous MOST publications on the specified SNR as follows (given for known SNRs only, i.e., objects with snr_status='k'):
