Predicted 1σ upper limits on the value of the hydrostatic bias b here represented as the ratio between the nonthermal (P_NT) and total (P_tot) pressure in the ICM (b = P_NT/P_tot; see e.g., Eckert et al. 2019; Ettori & Eckert 2022). The dashed line represents the upper limit when only the temperature profile was used in the likelihood; when the new universal pressure profile also formed X-COP data (see Appendix B), the upper limits indicated with a dotted line were obtained. We note that the high level of nonthermal pressure support required for A2319 is explained by the ongoing merger described in Ghirardini et al. (2018).
