Mass distribution for spirals in the post-merger and relaxed cluster samples within 0.9R₂₀₀, the aperture we use to compute fractions throughout this work. The inset p value denotes the Kolmogorov-Smirnov test significance under the null hypothesis that the stellar mass distributions from both cluster samples are drawn from the same parent distribution. The vertical solid and dashed lines indicate the median quantities for galaxies in the post-merger and relaxed clusters, respectively.
