Effect of redshift errors on the projected two-point correlation function estimate. Top panel: projected two-point correlation function from HMDPL halos. Blue data points are the two-point correlation function estimate from the halo distribution without redshift errors, and orange data points are this estimate including redshift errors. The solid curve shows the predicted dark matter two-point correlation function scaled by computed from the halo masses. Bottom panel: relative difference between the measured and predicted two-point correlation functions.
