The steps involved to perform an analysis
are outlined below.
Event ListFirst, a series of events must be given. These can either be written directly into the event list field, or be copied-and-pasted from a text editor. The format is YYYY MM DD hh mm ss, where each event is given on a separate line. All times are in UT.The dates are read from left to right which means that not all fields needs to be specified. For example, the two events 2000 07 12 15are both valid. The first event time will be July 12, 2000, 15:00 UT, and the next will be March 21, 2000, 12:01 UT. The events need not to be ordered in time. If three or less events are entered then
one curve for each event will be plotted. If more than three events are
selected then only the statistics will be plotted. See the plot figures
at the end of this document for an illustration.

Event WindowBased on each event in the event list a number of time periods of data will be loaded from the SAAPS database. The event window specifies the start and end time for each period relative to the times in the event list. The start and end times can be given in minutes, hours, or days. |

FieldAfter a database object has been selected the data fields are displayed in the field list. Select one field.Plot EventsPush this button to plot the events. The plot will appear in a new window. The plot itself can be modified from a menu bar in the plot window. Basic operations such as choosing line/points and setting scaling are available. |

Random ListIt is useful to compare the events with some randomly chosen events. These can be specified in the random list.Number of Random EventsInstead of manually typing in a random event list one can instead specify the number of random events that should be generated.Generate Random ListWhen this button is pushed a list of random events will be produced and displayed in the random list. These events can afterwards be edited.Plot Random EventsThis will produce a plot of the random events in a new window. |

Plot events windowThe figure below shows the plot of the two selected events with a time window of +/-12 hours. The plot shows the >10 MeV protons from the GOES-08 satellite for the July 14 and November 8 proton events. Time zero is relative the time of the two events. |
