correlation functions as a function of separation between grid cells. In the middle panel, the signal is shown after removing one column/row at the edge of the grid, while in the right-hand panel, the first two columns/rows are removed. The left-hand panel shows the nominal signal for reference. The errors indicate the scatter between the cosmic shear-reduced bootstrap realisations. The middle row shows the weighted mean of and its 68% confidence intervals, determined using all radial bins up to the one of interest. The bottom row shows the p-values of the null hypothesis, with the solid black (red-dashed) line for ().
