NIKA tSZ surface brightness at 150 GHz, maximum likelihood tSZ map and residual (top row) and Planck Compton parameter map, maximum likelihood Compton parameter map and residual (bottom row) computed from a non-parametric model based MCMC analysis. The residual maps does not indicate any significant substructure since no S/N over 3 is observed. The NIKA beam at 150 GHz and the Planck effective beam of 10 arcmin FWHM are shown in the bottom left-hand corner of the top and bottom row maps, respectively.
