tSZ azimuthal profile of A2319. The black samples show the measured tSZ signal in the MILCA map, and the green, red, and blue solid lines plot the GNFW, GNFW+δ (extra outer slope), and GNFW+Sh (shock) best-fit models for the full azimuthal profile, 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. From left to right and top to bottom, we present the profiles in the four quadrants: northeast, southeast, southwest, and northwest.
