Fraction of red spirals as a function of σ_cl and L_X, separated into a relaxed cluster sample (red open diamonds) and a merging cluster sample (filled grey diamonds). The solid black and red lines indicate the average fraction for relaxed and merging clusters, respectively. The dotted lines correspond to the 1σ error for each respective sample. A3667 has a marginally higher fraction of red spirals compared to relaxed clusters.
