Notes. The columns are the following: (1) MCSNR identifier, in the form JHHMM−DDMM. (2) Old “common” name used in the literature. (3) and (4) Position of the remnant, in J2000 equinox. (5) SNR extent using radio, optical, and X-ray emission (see Sect. 4.1). Major and minor axes are given in arcsecond. The error in diameter is usually smaller than 2′′. (6) Position angle of the SNR, in degrees, increasing in the north-east-south direction. A 0 value is given in circular cases. (7) Average size in parsec, assuming a common distance to all sources of 60 kpc. (8)LX, the X-ray luminosity in the 0.3–8 keV band, in units of 1035 erg s−1, obtained asdescribed in Sect. 4.3.1, at 60 kpc. (9) NH fraction, as defined in Sect. 4.9. Uncertainties are given at the 90% C.L. (10) 1 GHz flux density in Jansky. Errors are typically less than 10%. (11) Radio spectral index with corresponding uncertainties. (12) 1 GHz surface brightness. (13) Optical [S II]/Hα ratio measured in MCELS images. [O III] indicates that the given SNR is dominated by [O III]λ5007Å emission. (14) NOB, the number of blue early-type stars within 100 pc of the remnant, and (15) r, the ratio of CC SNe to thermonuclear SNe expected from the observed distribution of stellar ages in the neighbourhood of the remnant, as obtained by Eq. 3 (see Sect. 4.7). (16) “Hints” to the type of SN progenitor, based on spectral properties, local star formation, and a combination of both, as described in Sect. 4.7 and Tables 4 and 5.
