Third-order aperture masses from our modelling pipeline using B IHALOFIT (Eq. (31), blue) compared to the ones measured directly from the MS. The direct measurements on the convergence maps (Eq. (25)) are shown in green, and the measurements converted from shear 3pcf (Eq. (35)) are shown in orange. Both statistics were computed from 32 lines of sight of the MS, the error bars denote the error on the mean. We note that for the largest angle of 32′, a direct measurement could not be obtained due to the limited size of the individual light cones.
