Scientific paper

The use of the dependence of surface brightness (Sigma) on diameter (D) to estimate the distance to SNRs is examined critically, focusing on the finding of Green (1984) that the SNR distance calibrators with the most reliable distances are precisely the ones for which the Sigma(D) dependence is weakest. Observational data are compared in graphs, and a Sigma(D) distance relation based only on shell-type SNRs in relatively dense media is proposed.
