Comparison between the diagonal values of different covariance matrix estimates of the redshift-space transverse (solid lines) and radial (dashed lines) wedges of the spectroscopic cluster catalog. Blue and green lines refer to the bootstrap and jackknife covariance matrix, respectively. Black lines refer to the theoretical covariance matrix by Grieb et al. (2016), comprising both the shot noise (SN) and cosmic variance (CV) contributions, while red lines include only the contribution of cosmic variance.
