2.7.1 spase://NASA/Catalog/STEREO/IMPACT/LET/SEP Automatically generated event list for STEREO-LET 2026-03-01T18:13:51 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. spase://SMWG/Person/Andrew.J.Davis Publisher spase://SMWG/Person/Olga.y.Uritskaya MetadataContact spase://SMWG/Repository/CALTECH https://izw1.caltech.edu/STEREO/DATA/LET/Public/EventList/LETEventList.txt Text.ASCII spase://SMWG/Instrument/STEREO-A/IMPACT/LET EnergeticSolarParticleEvent 2007-01-05T12:00:00 2011-06-19T12:00:00 Evt # Event number Housekeeping Start time Temporal End time Temporal Peak Proton Intensities p/(cm2sr s MeV) 1.8 - 3.6 Other Peak Proton Intensities p/(cm2sr s MeV) 4 - 6 Other Peak Proton Intensities p/(cm2sr s MeV) 6 - 10 Other Peak Proton Intensities p/(cm2sr s MeV) 10-15 Other Proton Fluences: p/(cm^2 sr MeV) 1.8 - 3.6 Other Proton Fluences: p/(cm^2 sr MeV) 4 - 6 Other Proton Fluences: p/(cm^2 sr MeV) 6 - 10 Other Proton Fluences: p/(cm^2 sr MeV) 10 - 15 Other 2-Point Index (Value +/-) Other He/H @1.8-3.6 (Value +/-) Other Type Remark
