All Tables

Table 1: Newly determined centre positions and angular dimensions $\Theta _{\rm maj}$ and $\Theta _{\rm min}$ of all 36 Galactic supernova remnants that can be found in the area observed for the CGPS. Equatorial coordinates (J2000) are given in [hh mm ss] for Right Ascension and in [+dd mm] for Declination. The dimensions were determined from the radio emission as seen at 1420 MHz except for DA 530 and G156.2+5.7 (marked with ^*), which are only covered by the 408 MHz survey. The designations of 1420 and 408 MHz CGPS mosaics are given in the last column (see text).
Table 2: 408 MHz flux density values for point sources seen along with the SNR. These fluxes are predicted from the spectra published by Vollmer et al. (2005), except for ^*, where the Northern VLA Sky Survey (NVSS, Condon et al. 1998) was used at 1420 MHz, and the Westerbork Northern Sky Survey (WENSS, Rengelink et al. 1997) at 327 MHz.
Table 3: Flux densities integrated at 1420 MHz and 408 MHz taken from the CGPS. Spectral indices $\alpha$ are listed assuming $S\sim \nu ^\alpha$ . The spectral index $\alpha _{\rm all}$ fitted to all flux densities by an error-weighted least square fit is listed in Col. 4 and the spectral index calculated between our two values $\alpha _{\rm CGPS}$ is listed in Col. 5. The flux densities we used to calculate $\alpha _{\rm all}$ were taken from the references listed in Col. 6 and references therein.
Table 4: Polarization properties of the supernova remnants. The polarized intensity was corrected for noise bias (see text Sect. 3.2). The peak polarization in Col. 4 is an approximate value. SNRs with no detectable polarization were removed from the table.
