Relationship between the SFR surface density and the gas surface density, Σ_SFR−Σ_gas, in the model without bar (RA) at a single time, 1.2 Gyr for a variety of spatial scales over the disk. In the top row color represents normalised density (from 0 to 1) with a given SFR and gas density; in bottom row color represents a mean gas velocity dispersion and contours show the values from 10 km s^-1 to 40 km s^-1 with a bin size of 5 km s^-1 . Panels from left to right: the K-S relationship using data from the entire disk; from the inner, r< 5 kpc; from the radii between 5 <r< 10 kpc; and from the outer parts of the disk, r> 10 kpc. The solid black line represents the K-S relation with a slope of 1.4 (Kennicutt 1998). The diagonal dashed lines cutting across each panel represents the star-formation efficiencies of 100%, 10%, 1%, 0.1% and 0.01% per 10⁹ yr.
