Flowchart of calculation procedures of WASAVIES-EO. The pastel green, cyan, and yellow boxes indicate the real-time analysis procedure, model or code, and data or database, respectively. The boxes in the blue frame are used in the original WASAVIES, while those with red frame are newly implemented in WASAVIES-EO. All databases included in the gray box are used for calculating the best-fit IP, θ_t, γ, and N₀, while only the database of SEP fluxes at 1 AU is used for calculating SEP flux outside satellite. The Kp index is automatically updated at intervals of 3 h.
