Radius–velocity relation of H i SNRs. The grid is for E 51 = 1. The grid shifts along lines of constant δ for different E 51 but not much: e.g., for E 51 = 0.1, the lines of constant t/ t sf shift down by 36%. The thin grid lines in δ are drawn at 20, 30, and 50% of the thick-grid intervals, while those in t/ t sf are at every 10%. The four H i SNRs identified in the I-GALFA survey are marked.
