The CHMFs in five different redshift bins. The red points with error bars show the CHMFs obtained from the weak-lensing ESD measurements. The black dashed lines show the CHMFs obtained from the group catalog of Y21, with a correction using Equation (14). The black solid lines show the theoretical CHMFs using fitting functions from Tinker et al. (2008) under the Planck18 cosmology.
