Abstract

We present griz photometric light curves for the full 5 years of the Dark Energy Survey Supernova program (DES-SN), obtained with both forced Point Spread Function (PSF) photometry on Difference Images (DIFFIMG) performed during survey operations, and Scene Modelling Photometry (SMP) on search images processed after the survey. This release contains 31,636 DIFFIMG and 19,706 high-quality SMP light curves, the latter of which contains 1635 photometrically-classified supernovae that pass cosmology quality cuts. This sample spans the largest redshift (z) range ever covered by a single SN survey (0.1More
