Upper panels: simulated NIKA2 tSZ surface brightness maps for a relaxed (left) and a disturbed (right) cluster. The signal-to-noise contours (black lines) start at 3σ with 1σ steps. Lower panels: pressure profiles estimated at the maximum likelihood from the MCMC analysis of the maps shown in the above panels (black line) and associated 1 and 2σ uncertainties (dark blue and light blue regions). The pressure profiles extracted from the MUSIC simulation for each cluster are represented by the red dots with 1σ error bars. A radius of 100 kpc corresponds to an angular scale of 15.3 arcsec and 12.8 arcsec for the left and right panel, respectively.
