Best-fit parameters of the joint gNFW fit to Bolocam and Planck. The normalization P₀ (top row) and outer logarithmic slope β (bottom row) were allowed to float, while C₅₀₀, α, and β were fixed to the A10 values using a prior on ﹩{\theta }_{{\rm{s}}}﹩ from Chandra. From left to right, the plots indicate cluster mass and redshift, with 68% confidence intervals of linear fits from LINMIX_ERR overlaid in orange. The legends in the upper right indicate the best-fit intrinsic scatter along with the probability that the slope is >0. At the median mass of the BoXSZ⁺ sample, the linear fits vs. M₅₀₀ provide values of P₀/P₅₀₀ = 9.13 ± 0.68 ± 2.98 and β = 6.13 ± 0.16 ± 0.76.
