Comparison of the main characteristics of the 2–1.2 mm color distributions of various catalogs.
| Catalog | Mean color | Median color | Standard deviation | KS p-value against N2CLS |
|---|---|---|---|---|
| N2CLS COSMOS | 0.222 ± 0.008 | 0.206 ± 0.007 | 0.070 ± 0.010 | |
| SIDES galaxies (COSMOS flux cuts) | 0.212 ± 0.003 | 0.205 ± 0.003 | 0.022 ± 0.003 | 2.2 × 10−11 |
| SIDES blobs (COSMOS flux cuts) | 0.240 ± 0.002 | 0.229 ± 0.002 | 0.062 ± 0.004 | 1.9 × 10−3 |
| SIDES E2E (COSMOS-like) | 0.238 ± 0.010 | 0.227 ± 0.010 | 0.063 ± 0.012 | 6.9 × 10−3 |
Notes. The N2CLS COSMOS catalog is the true catalog after selecting the high-reliability sources at both 1.2 mm and 2 mm (S/N ≥ 4.6). The SIDES galaxy and blob catalogs are both cut at the flux limit of the N2CLS COSMOS field (see Sect. 3.1). The SIDES E2E catalog is described in Sect. 2.5. For the true N2CLS data, the uncertainties on the mean, the median, and the standard deviation are derived using a bootstrap method. For the simulated data, we provide the standard deviation between the multiple COSMOS-like fields extracted from the full SIDES-Uchuu simulation. The impact of the photometric calibration uncertainties on the colors (∼7%, see Sect. 3.1) are not taken into account in this table. The last column presents the probability associated with the KS test between a given distribution and the N2CLS.
