Description

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.
