Description
In this paper, we present the most up-to-date list of nearby galaxies with optically detected supernova remnants (SNRs). We discuss the contribution of the H{alpha} flux from the SNRs to the total H{alpha} flux and its influence on the derived star formation rate (SFR) for 18 galaxies in our sample. We found that the contribution of SNR flux to the total H{alpha} flux is 5+/-5%. Due to the observational selection effects, the SNR contamination of SFRs derived herein represents only a lower limit.
