Standard deviation of the averaged ellipticity and aperture mass as a function of aperture size θ for the CNPT and MWK models: tangential ellipticity |$\langle \epsilon _+^2\rangle$| (solid green and magenta lines), radial ellipticity |$\langle \epsilon _\times ^2\rangle$| (solid red and cyan lines), aperture mass |$\langle M_\mathrm{ap}^2\rangle$| (dashed green and magenta lines) along with |$\langle M_\perp ^2\rangle$| (dashed red and cyan lines), all for the Euclid galaxy sample in comparison to the same quantities derived from the weak lensing convergence (corresponding black lines).
