Normalized differential number counts (S^5/2n(S)) from the Tucci et al. (2011) model (black lines) and observations (Planck, black points; ACT, cyan points; SPT, blue and green points) between 70 and 220 GHz. Red lines represent the model, but with the updated parameter values as described in the text. The very recent measurements from ACT at 148 GHz (cyan dots from Datta et al. 2019) and from SPT-SZ (green dots from Everett et al. 2020) are not used in the fit, but are shown for comparison.
