Fig. 3.


Posterior probability distributions for σap–mag scaling relation parameters, obtained as described in Appendix B, from velocity dispersion measurements of 58 cluster members in MACS 1206. The 16th, 50th and 84th percentiles of the marginalized distributions for the slope (α), normalization () and scatter around the scaling relation (Δσap) are quoted and shown as vertical dashed lines.
