This tool is based on physical modelling of a number of reference event profiles (six distinct types) as a function of distance from the Sun, and fitting the resulting fluence and peak flux spectra to a distance scaling law. A subset of the SEPEM reference event list were classified in terms of the six event types, resulting in a new event list to which the distance scaling relations can be applied. The event spectra at 1 AU were derived from the SEPEM reference proton dataset.
YYYY-MM-DD hh:mm:ss. Distances can be entered in any float format, and should be separated from the time stamp by at least one blank character. A sample set of two input lines would look like

Runbutton. The model name cannot be left blank. If a model with the same name is already stored in the database by the current user, the model results will be over- written.
Once the run has been started, no other activity (except browsing the help pages) is possible on the server (with the current user account) until the run is completed. While the process is running, a page is presented where the user can perform a refresh to check for completion, or kill the running process. The user can log out and return to the server later.
For comparison, the tool generates probability curves for three distance scaling laws:
At the top of the pane, links to two types of text files are provided:
The table labelled Probability curves provides access to plots of the probability curves for each data channel, accumulated over the entire mission.
The table labelled Mission profile provides access to plots representing the evolution of the 90% confidence level values over successive solar cycle phases. Please note that these plots are only provided for reference: the total mission fluence and peak flux is not simply the sum or the maximum of the quantities shown in the plots.
As for the models at 1 AU, plots of the fluence or flux distribution functions (plus comparisons and departures) and of the duration fits (plus departures) are produced, for both solar maximum and solar minimum conditions. As the number of plots is large, they are not presented in a table, but can be extracted from the output zip archive (see below).
All output files (PNG plot files and text files) can be downloaded as a zip archive using the Supplementary outputs link: this will open a new window with a summary of the results and a link to the Zip archive of output files. All files are stored in the database and can be retrieved at any time from the My SEPEM page.
