Strong lensing of tidal disruption events: Detection rates in imaging surveys

The unlensed and strongly lensed tidal disruption event (TDE) catalogs at the fiducial temperature of T = 20,000 K for the L1 and L2 luminosity models separately. The L1 luminosity model is an observationally driven upper limit defined by 1% of stellar fallback material (produced in the disruption of a 0.1 Msun main-sequence star) turning into radiation. The L2 luminosity model is defined by self-crossing shocks of stellar debris. Each line of a file represents a TDE (unlensed or lensed), so to compute the TDE detection rate one would need to iterate through the entire file, sum over the TDE weighting factors, and apply magnitude cuts according to the desired survey limit. For the lensed catalogs, further normalization by any oversampling factors is needed. These catalogs assume a survey area of 20,000 deg^2; the observational limiting magnitude is 27.0 (AB) for each band, so one can choose a brighter limiting survey magnitude with mag (AB) < 27.0.分别针对L1和L2光度模型，提供了基准温度T=20000 K下的非引力透镜化与强引力透镜化潮汐瓦解事件（TDE, tidal disruption event）目录。其中L1光度模型为基于观测约束的上限模型，其定义为：0.1倍太阳质量（M☉）主序星瓦解过程中产生的恒星回落物质，有1%转化为辐射能量。L2光度模型则以恒星残骸的自交叉激波作为定义基准。每个文件的每一行对应一个潮汐瓦解事件（非透镜化或强透镜化），若需计算TDE的探测率，需遍历整个文件，对所有TDE的权重因子求和，并依据预设的巡天极限星等执行星等截断操作。针对强引力透镜化目录，还需通过过采样因子进行额外的归一化处理。本套目录假设巡天面积为20000平方度（deg²），各波段的观测极限星等为27.0（AB星等），因此可选用小于27.0 AB星等的更严格巡天极限星等开展相关分析。
