Top panel: MILCA tSZ map of A2319. The solid and dashed white circles show the typical radius of the cluster, R₅₀₀, and the shock radius, R_Sh, detected in the azimuthal profile. The beam FWHM is given by the white circle in the bottom left corner, and the black contours provide the S/N in units of 2σ. The gray thin lines present the profiles for each quadrant of A2319. Bottom panel: tSZ azimuthal profile of A2319. The black samples show the measured tSZ signal in the MILCA map, while the green, red, and blue solid lines plot the GNFW, GNFW+δ (extra outer slope), and GNFW+Sh (shock) best-fit models, respectively. The vertical dashed gray line corresponds to R_sh = (2.93 ± 0.05) R₅₀₀. The residual, normalized by the error bars, χ, is also shown for all the models.
