Fig. 6
Comparison of the σgal − kT300 kpc scaling relation of this work with prior literature, as labeled. Shaded regions are 1σ uncertainty on the expected velocity dispersion at given temperature. The magenta line is the locus of constant specific energy ratio,
with μ = 0.6. The slope ofWilson et al. (2016) suffers from a potential bias discussed in the text.
