摘要

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