Star formation relation and emission line maps used to obtain the location of the regions considered in NGC7130. Top panels: Same as Fig. 1, but applying the MARS method to the log₁₀Σ_H2. Bottom panels: ALMA CO(2–1) (left) and HST/NICMOS Paα maps (right). This last map is smoothed to the ALMA resolution. The magenta filled ellipse (bottom left) represents the beam size (0″.36 × 0″.29 PA = 69°).
