摘要
我们呈现暗能量探测超级新星计划（DES-SN）全 5 年的 光度曲线，这些数据通过在调查期间对差分图像进行强制点扩散函数（PSF）光度测量，以及在调查结束后对搜索图像进行场景建模光度测量（SMP）获得。本次发布包含 条 SMP 光度曲线和 条高质量 SMP 光度曲线，后者包含 条经光度鉴定确认的超级新星且通过 cosmology 质量裁剪。该样本涵盖了单一超级新星调查所覆盖的最大红移（）范围（），是单一仪器获取的超级新星样本中最大的单一样本，可用于宇宙学约束。我们详细描述了获取最终 DES-SN 光度测量所做出的改进，并与用于 DES-SN3YR 光谱确认的 SN Ia 样本进行比较。我们还包括对 SMP 光度测量相对于真实-time DIFFIMG 强制光度测量性能的比较分析，发现 SMP 光度测量更精确、更准确、对主机星系面积亮度异常更不敏感。光度曲线及附加数据的公开发布可在 https://github.com/des-science/DES-SN5YR 找到。最后，我们讨论了对未来瞬变调查（如即将推出的 Vera Rubin 观测台遗产太空时间（LSST））的含义。
