Input (dotted line) and reconstructed (various colours and linestyles, see legend) two-point correlation function obtained using the various estimators available in the literature for a cubic geometry (left) or a realistic (BOSS DR9) survey volume (right). The bottom panels show the root mean square of each estimator with corresponding colour and linestyle. In each case, the Hamilton and Landy-Szalay lines are exactly superposed as well as the Davis-Peebles and Hewett lines. (Coloured version of the figure available online).
