Summary: 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 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, apply magnitude cuts according to the desired survey limit and then 
normalize by any oversampling factors (only relevant for lensed catalogs). These 
catalogs assume a survey area of 20,000 deg^2; no magnitude cuts have been 
applied, so one can choose a limiting survey magnitude. 

-----------------------------------------------------------------------------------
Notes for all files: the weighting of each TDE needs to be accounted for post-
processing, and 'band' in the file name can be either u, g, r, or i.
