Models at 1 AU
On this page, the outputs from the statistical models can be viewed in
more detail, in the form of
For models based on proton spectra, an abundance scaling to five ion
species can be performed as well.
After selecting a previously run model, the page reloads to display
Once all mandatory selections have been made, the
- Model type: select between cumulative (not available for all
model types) and worst case.
- Confidence level: the model results will be calculated for
confidence levels 75%, 90%, 95% and 99% by default; one additional
confidence level can be specified by typing a value in the text box
(between 50% and 99%).
- For models based on a proton flux spectrum, the flux/fluence outputs
can be scaled to flux/fluence of the following ion species: He, C, N, O,
Fe. The scaling is achieved by applying the ECSS-E-ST-10-04
(ECSS standard for Space Engineering: Space Environment)
abundance ratios to the proton fluxes/fluences.
button can be pressed to generate the resuls.
The format of the results depends on the statistical model type.
For time above threshold and event duration models, and for flux/fluence
model based on a response function, the output is a
series of curves of the model parameter as a function of mission length,
for each confidence level. The results are presented as an on-screen
table, a data file and a plot.
For flux and fluence models, the outputs consist of a series of
particle spectra as a function of energy. The spectra are grouped by
confidence level and mission length. The results are presented as an
on-screen table, a data file and a series of plots (one per confidence
For flux and fluence models based on proton spectra, the original
probability curves (at lower resolution) are reproduced after abundance
scaling to the selected ion species.
