The covariance matrices (solid line) and C_i,j (dashed line) of the estimators and ŵ_i, for i = 2 associated with the angular bin 2 < θ < 3.2 arcmin, as a function of j. We show the results obtained for halos in the redshift range 0 < z < 0.8, with an angular window of 400 deg², above the mass thresholds M _∗  = 2 × 10¹³ and 10¹⁴   h^-1   M_⊙, from bottom to top. Here we only consider the low-order contributions, given by Eqs. (93) and (94).
