Comparison between N2CLS GOODS-N (orange diamonds) and COSMOS (red diamonds) source number counts at 1.2 mm (top panels) and 2 mm (bottom panels). Differential and cumulative number counts are presented in the left and right panels, respectively. In each panel, the N2CLS galaxy number counts (see Sect. 4.3) and the corresponding 1 σ confidence interval are represented using red (COSMOS) and orange (GOODS-N) solid lines and shaded regions. All results from interferometric observations at 1.1 or 1.2 mm (Fujimoto et al. 2016, 2023; Hatsukade et al. 2016, 2018; Umehata et al. 2017; González-López et al. 2020; Gómez-Guijarro et al. 2022a; Chen et al. 2023) and 2 mm (Zavala et al. 2021; Chen et al. 2023) are shown as open circles. The measurements from single-dish observations at 1.1 or 1.2 mm (Lindner et al. 2011; Scott et al. 2012) and 2 mm (Staguhn et al. 2014; Magnelli et al. 2019) are represented by filled squares.
