Mean SFR per stellar-mass bin of equal logarithmic width for the FIR-emitter sample (squares) and the combined FIR plus Hβ no-FIR sample (circles) using identical mass bins for both. The number of galaxies per bin for the FIR-only sample is [2, 14, 12, 29, 4], and for the combined sample, it is [11, 17, 20, 30, 16]. Filled symbols include sources affected by FIR upper limits, while open symbols show the results after excluding them. Error bars indicate the 68% central interval of the SFR distribution within each bin. The dotted green line and contours represent the star-forming MS ±1σ at z ∼ 0.9 from Popesso et al. (2023). The solid orange line shows a Popesso-like fit to the FIR-only binned data, with log(SFR_max) = 1.51 and γ = 1 fixed, following the parametrization in Table 2 of Popesso et al. (2023). The dotted orange line shows the same fit after excluding sources affected by upper limits.
