Notes. μ and σ are the mode and the standard deviation of the probability distributions. The two values reported for σ in the case of split-normal priors represent the standard deviations of the lower and upper halves of the corresponding distributions. The parameters (RA, Dec)gNFW, Pe, us, and Te, us respectively define the centroid of the gNFW profile describing the upstream pressure distribution, and the upstream pressure, and the temperature normalization (see Sect. 2.2.2 for a discussion). For the shock front, we use its nose position (RA, Dec)shock as the reference point. Further, θ and ℳ are the orientation of the shock axis and the Mach number (Sect. 2.2.1), while α is the slope of the downstream power-law profile (Sect. 2.2.2). Finally, κACA and κALMA are the ACA and ALMA calibration hyperparameters (Sect. 2.2.2).
