PSF tool kit, status and performances

We describe the status of PSF modelling for SPV3, providing updates and features that may be used in multi-faceted investigations.

Weak Lensing End2End box, status and performances

We are currently working on propagating expected Euclid PSF errors into shear biases for the WL E2E box as part of the SPV3 exercise. Given some base and perturbed PSFs generated using the PSF Toolkit, we numerically estimate the multiplicative and additive shear biases for galaxies in the Flagship 2 mock catalogue. We currently consider two sources of PSF error: firstly, errors in the PSF...
