Empty points represent the light-cone halo N(M), the red curve shows the volume-integrated Reed et al. (2007) Φ(M, z), the blue line shows the Jenkins et al. (2001) Φ(M, z), and the black curve represents the double power-law Schecther function. The lower panel shows the relative deviations of the three models from the data N(M), with the filled black points representing the deviation of our Schechter-like function. It is evident that the latter functional form represents the data better. The two theoretical Φ(M, z) are the best fits to the halo data from six models.
