ZTF's scene modeling photometry, compared against its forced photometry release, shows a new CCD pocket effect that adds up to 7% flux-dependent nonlinearities and makes the DR2 supernova light curves unusable for precision cosmology until reprocessed.

ZTF SNe Ia DR2: Towards cosmology-grade ZTF supernova light curves using scene modeling photometry
ZTF's scene modeling photometry, compared against its forced photometry release, shows a new CCD pocket effect that adds up to 7% flux-dependent nonlinearities and makes the DR2 supernova light curves unusable for precision cosmology until reprocessed.
