Five nearby and extended clusters not included in the PSZ catalogue: the Perseus cluster and Abell 1060 (in the point-source mask); Ophiuchus cluster and 3C 129.1 (in the Galactic mask); and Virgo cluster (below the S/N threshold of the catalogue). Top panels: reconstructed thermal SZ maps from the MILCA algorithm (Hurier et al. 2013). The dashed circles represent the apertures of θ₅₀₀ from the MCXC catalogue. Each SZ-map covers an area of 4θ₅₀₀ × 4θ₅₀₀. Bottom panels: composite images of the optical (DSS, white), X-ray (ROSAT, pink) and SZ signal (Planck, blue). The sizes of the composite images are 2° × 2° for Perseus; 1° × 1° for A1060; 1° × 1° for Ophiuchus; 0.77° × 0.77° for 3C 129.1 and 3.84° × 3.84° for Virgo. The black and white circles picture a 10 arcmin aperture, but for Virgo for which the aperture is 30 arcmin.
