The SEPEM server provides access to a variety of spacecraft data and to
processing and modelling tools. This page provides an overview of the
functionalities implemented on the server.
All channels of the various instrument datasets can be plotted on the
Browsing & plotting page. A limited
download capability is provided as well.
Data Table Manager
The server provides a number of functionalities to process data tables.
A number of these operations involve changing the content of data
tables, which is only allowed for tables that have been created by
the current user. A table copy function
is available to create a user owned version of any data table in the
A number of processing tools are available to prepare the data for usage
with the effects tools and statistical models:
Event List Manager
SEP event lists can be generated on the fly
using any data channel available on the system, or using a
Particle fluence and peak flux spectra can be
generated for any event
list on data tables that provide more than two energy channels for a
given particle type; analytical spectrum fits can
be superimposed on the plots.
The SEPEM server implements a number of
tools to generate
Fluxes and fluences in free space can be folded with a geomagnetic transmission function for spacecraft trajectories in the Earth's magnetosphere.
spacecraft trajectory frame is integrated within the
statistical models page.
- fluence and peak flux models: generate
probability curves from dataset tables or
response functions for a
user selected event list;
- time above threshold analysis:
generate probability curves for exceeding a data channel or response
- event duration analysis: generate
probability curves for the mission time spent during events.
Post-processing page, the statistical
models can be visualized for selected confidence levels. In addition, He flux/fluence probability curves can be converted to ion values using ion abundance ratios.
Apply response function page, an existing
response function can be applied
to particle flux/fluence statistical models.
Away from 1 AU modelling
SEPEM contains a statistical SEP model that makes use of the results of
a shock-and-particle propagation physics based model to estimate event peak
intensities and fluences from 0.2 to 1.6 AU.
- Event spectra: browse the
event spectra that are used for the helioradial distance scaling
- Create models:
perform a statistical analysis using a mission time profile.
The My SEPEM page provides quick access to all
results generated and stored by the current user.
Every operation that creates new content or alters existing content in
