GMOS spectra from four of the SNRs with diameters of ﹩\lt 0\buildrel{\prime\prime}\over{.} 5=11﹩ pc. B12-174a (bottom trace) is the only one with broad lines characteristic of fast-moving ejecta. The other three are typical; none of them show broad lines, and all have [S II] ﹩\lambda \,6716/\lambda \,6731﹩ ratios indicating relatively high density. The traces have been scaled and vertically offset for clarity.
