Correction for the noise correlation and interpolation kernel. Multiplicative (left panels) and additive (right panels) shear bias differences obtained employing a Euclid/VIS pixel scale of $0\stackrel{″}{.}1$, a lanczos15 interpolation kernel, when we account for the impact of noise correlations in the S/N matching between the D and E images (test Ic), as described in Sect. 5.2. The data points show the bias obtained from the fit with the error bars indicating 1σ uncertainties for a number of galaxies N_gal ≃ 1.4 × 10⁶ for each S/N. For comparison, the shaded area indicates the requirements on uncertainty on the μ and c biases arising from the total shear measurement process for an Euclid-like survey (Cropper et al. 2013).
