摘要
我们发布了来自利克天文台超新星搜寻（LOSS）后续观测计划、在2003年至2020年间观测的70颗剥离包层超新星（SESNe）的BVRI与无滤光Clear光变曲线。我们的SESN样本包含19颗光谱正常SNe~Ib、2颗特殊SNe Ib、6颗SN Ibn、14颗正常SNe Ic、1颗特殊SN Ic、10颗SNe Ic-BL、15颗SNe IIb、1颗模糊的SN IIb/Ib/c，以及2颗超亮超新星。我们的后续测光（按每颗超新星计）平均覆盖81个测光点（中位数为58个点），平均观测节奏为3.6天（中位数为1.2天）。从我们的完整样本中，有38颗超新星的子集在至少一个波段具有极大前覆盖，使得该子集中每颗超新星的峰值亮度能够被定量确定。我们描述了数据收集与处理技术，重点介绍我们的自动化测光流水线，并由此导出公开可用的数据产品，以促进和鼓励学界进一步研究。利用这些数据产品，我们通过经验色演化关系推导出宿主星系消光值，并首次在光学与红外波段对大样本SESNe给出精确的上升时间测量。通过多波段光变曲线建模，我们发现SNe Ic往往比SNe~Ib和IIb具有更低的外抛物质质量与更低的外抛物质速度，但具有更高的Ni质量。
