Notes. In the upper part of the table, we list all systematic uncertainties, which ultimately translate into an uncertainty in the weak lensing mass measurement, where we added the individual contributions in quadrature to obtain an estimate for the total uncertainty. We report the relative uncertainties in percent in the second column, the resulting relative uncertainty on the mass in the third column, and refer the reader to the respective sections or appendices listed in the last column for more detailed information about the contributions to the error budget. In the lower table, we list statistical uncertainties in the redshift distribution, which affect the calculation of the average geometric lensing efficiency ⟨β⟩ for individual cluster fields. We note that the final statistical uncertainties reported in Tables 6 and 7 do include additional contributions from shape noise and uncorrelated large-scale structure projections.
