Galaxy number counts at 350, 500, and 850 μm. The model we used (Béthermin et al. 2012a) is shown with the continuous line. It agrees very well with the most recent Béthermin et al. (2017) model (SIDES, long-dashed line). Measurements are from Herschel at 350 and 500 μm (Oliver et al. 2010; Clements et al. 2010; Glenn et al. 2010; Béthermin et al. 2012c), SCUBA2, and ALMA at 850 μm (Geach et al. 2017; Béthermin et al. 2020), and Planck at very bright fluxes (Planck Collaboration Int. VII 2013). The models are below the Herschel measurements at intermediate fluxes because these measurements are biased high due to the relatively low angular resolution combined with galaxy clustering (as demonstrated in Béthermin et al. 2017).
