The fluence (in cm^–2 sr⁻¹) of the SEP events in the SEP part of the database for various integral energies (>10; 30; 60 and 100 MeV) as a function of the SXR peak flux (in W/m²) (A); the duration of the associated parent solar flares (in minutes) (B); the rise time of the associated parent solar flares (in minutes) (C) and the longitude of the parent solar flare (in W/m²) (D). (A) Incorporates the class, i.e. C, M, X and X10, of solar flares on its top part.
