From top to bottom: NIKA2, MUSTANG, Bolocam, and Planck tSZ data (left), maximum likelihood tSZ map (middle), and residual (right) computed from an MCMC analysis based on a non-parametric model and masking the over-pressure region in the south-west of PSZ2 G144.83+25.11. The Bolocam row is shown as a cross-check even if this data is not used for this analysis. The significance contours start at 3σ with 1σ increments. A 4σ tSZ signal isidentified in the NIKA2 residual map within the region that is masked for this analysis.
