Left panel: K-S relation plot for NGC 3627 at the resolution of 82 pc. Σ_H2 was derived from the ¹²CO(1−0) emission line map and Σ_SFR from the Hα image based on Eqs. (2) and (5), respectively. Red triangles indicate data points above 3σ significance both in Σ_H2 and Σ_SFR, within a radius of 1.3 kpc (on the plane of the galaxy). The solid black line indicates the OLS bisector fitting line (see Sect. 3.7 for fitting method). The index N_fit and the intercept A_fit of the OLS bisector fitting line, the Pearson correlation coefficient r_core, and τ_depl values are reported in figure. Right panel: same as left panel with Σ_H2 derived from the ¹²CO(2−1) emission line map based on Eq. (3) at the resolution of 36 pc. Red triangles indicate data points above 3σ significance both in Σ_H2 and Σ_SFR, within a radius of 1.1 kpc (on the plane of the galaxy).
