Polarization properties of the supernova remnants. The polarized intensity was corrected for noise bias (see text Sect.\u00a03.2). The peak polarization in Col.\u00a04 is an approximate value. SNRs with no detectable polarization were removed from the table.<\/p>\n

G83.0-0.3 is listed by Green (2004)<\/a> as a possible<\/i> SNR originally reported by Taylor et\u00a0al. (1992)<\/a>. No study since then has confirmed its non-thermal nature. It has the structure of a shell of small angular size (Fig.\u00a02<\/a>). It lies within the confusing and highly structured background of Cygnus\u00a0X, and sits atop a filament of thermal continuum emission. A single, flat-spectrum point source is within the remnant’s boundary, and after removing its flux, we integrated 408, 1420, and\u00a02695\u00a0MHz (11\u00a0cm Effelsberg Survey, <\/a>F\u00fcrst et\u00a0al. 1990<\/a>) data and used the point source corrected 327\u00a0MHz value from Taylor et\u00a0al. (1992)<\/a> to confirm a non-thermal spectrum for G83.0-0.3 (Fig.\u00a08<\/a>). Taylor et\u00a0al. (1992)<\/a> measured a flux at\u00a04850\u00a0MHz from the Green Bank survey (<\/a>Condon et\u00a0al. 1989<\/a>). However, in these data we find that the aforementioned thermal background dominates, and one cannot extract a reasonable flux for the SNR alone due to the low resolution of the data.<\/p>\n<\/div><\/div><\/div>
