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.
