PAH_3.3 emission maps for all galaxies in the sample. For each galaxy, an RGB image composite of F070W (blue), F115W (green), and F200W (red) filters with the 5σ significance PAH map of the galaxy (superimposed in purple) is shown on the left. The red ellipses indicate the galaxy disks. The arrow indicates the RPS direction. The surface brightness map of the PAH_3.3 emission is shown on the right. The gold and blue contours indicate the leading and trailing galactic regions with brightness greater than 5σ_bkg, respectively. The A_RPS is the ram pressure asymmetry of the PAH map as defined in Sect. 4.1.1. The blue hatched region in galaxy 10685 represents the masked area. North is up, east is left.
