Biases of the point estimates ĝ₁ on Euclid-like simulations of galaxies with shape parameters drawn from the GEMS catalog. In both panels, each point represents a case consisting of one particular galaxy, and the shear bias is computed by averaging over 10 000 rotated realizations of this galaxy (the data structure follows Fig. 2). For clarity, only cases with ⟨S/N⟩> 10 are shown. In the right panel, the amplitude of the shear bias is shown as function of half-light radius R and the noisy measured adamom_sigma taken from a single realization of each case.
