The automatically generated event list for the STEREO Low Energy Telescope (LET) identifies Solar Energetic Particle (SEP) events and Co-rotating Interaction Regions (CIRs) based on specific proton rate thresholds and spectral characteristics. Automatically generated event list for STEREO-LET, requiring that 3-hour averaged 1.8-3.6 MeV proton rate exceeds 5x10^-4 particles/(cm^2 sr s MeV) Peak Proton Intensities often occur at different times for each energy bin. Proton fluences have had a constant background assumed to be 2.3x10^-5 particles/(cm^2 sr s MeV) subtracted. The "2-Point Index" is obtained from the 1.8-3.6 and 4-6 MeV proton FLUENCES. The He/H ratio is that of the 1.8-3.6 MeV/n proton and He FLUENCES, where a constant background of 1x10^-5 particles/(cm^2 sr s MeV/n) has been subtracted from the He. Uncertainties in the index and He/H are statistical errors ONLY. Event Types are tentative identifications ONLY, automatically determined based on spectral hardness and He/H ratio. Events with an added "?" fall within one standard deviation of the chosen boundary between SEPs and CIRs in at least one parameter (index or He/H). An "e-" after the type indicates that the peak of an SEPT electron event falls between the event start and end times.
