... One of the objectives of this work is to derive radial distribution of supernova remnant surface densities in spiral galaxies. ... Other objectives include the comparison of the SNR radial distribution with the radial distribution of HII regions to look for any association between Type II progenitors and the SNRs and comparison of the SNR distribution to the spiral arm patterns. ... Knowing the positions of the SNRs, we can compare their distributions relative to HII regions and spiral arms. ...
