Best-fitting pressure profile parameters considering, (i) a GNFW profile, (ii) a GNFW profile and an outer slope, and (iii) a GNFW profile and a shock.

| GNFW+Sh (Eq. (5)) | 8.82 ± 0.20 | 1.10 | 1.05 | 4.295 ± 0.038 | 0.23 | 2.93 ± 0.05 | −0.012 ± 0.045 | β | 1.1 | 33 |
Notes. Only β and P0 are fitted for model GNFW, and we fixed α, γ, and c500 to the values derived in Ghirardini et al. (2018) for the same cluster. Uncertainties are computed as the second-order momentum of the likelihood function.
