Abstract Anderson et al. identified 76 candidate supernova remnants (SNRs) using data from the H i/OH/Recombination line survey of the Milky Way. The spectral index and polarization properties can help distinguish between SNRs and H ii regions, which are often confused. We confirm two SNR candidates using spectral index data and morphology. However, we observe that the fractional linear polarization cannot distinguish between SNRs and H ii regions, likely due to contamination by diffuse Galactic synchrotron emission. We also comment on the association of SNR candidates with pulsars through geometric and age considerations.
