Example eigenPSFs extracted from the MCCD-HYB PSF model trained on the simulated dataset with a S/N of 70. The local eigenPSFs were extracted from the graph’s spatial constraint of a central CCD. It can be seen from the eigenPSFs that the global model is specialising on the shape of the PSF while the local model specialises on capturing its ellipticity. It is also worth to mention that the first global eigenPSF found on the first row provides the baseline isotropic PSF the model uses. (a) Global eigenPSFs. (b) Local eigenPSFs.
