Pixel-by-pixel star-formation relations of and Σ_SFR at different resolutions show large scatters at small scales and tighter relations at larger scales. The contours represent source number densities of 1, 3, 5, 10, 20, 40, 60, and 80 data points at the binning of 0.2 in and Σ_SFR. The same color represents the same number density in all of the plots. The three dotted lines show lines of constant depletion time with t_dep =10⁸, 10⁹, 10¹⁰ yr from top to bottom. The horizontal and vertical dashed lines show the 3σ detection limit for Σ_SFR and  respectively.
