KS law (solid magenta line; Heiderman et al. 2010). The coloured points represent the location on the KS plane of the subset of ALPINE galaxies analysed by Béthermin et al. (2023). Each galaxy is resolved in two different beams, providing two measures for Σ_gas and ∑_SFR. Following the notation of Ferrara et al. (2019), this corresponds to a burstiness parameter k_s = 0.34 (purple line). For comparison, we also report the relation obtained by substituting k_s = 5 and 10 in Eq. (5) with dashed orange and dotted yellow lines, respectively. The y dispersion is σ = 0.28.
