Window size: Size (span) of the windows containing data for the analysis. If "TIME" time-mode is selected, the given value  corresponds to the duration of each dataset, in days. If "EVENTS" events-mode is selected instead, the given value corresponds to the number of events that each dataset contains (see Figure 3 caption for details). Finally, if the "FRONT" front-mode mode is selected, the given value corresponds to the meters of front advance, i.e. a subsequent time window start at the time when the front advance is moved as much (in meters) as this value indicates from the position it was in the beginning of the previous time window. Therefore, in this case, nor the number of events neither the time range will be equal in the datasets.

Period length (for exceedance probability): Duration of time period for which exceedance probability will be estimated for the magnitude specified above above.

Figure 3.The time window step is set to 5 days in both cases. Notice that the each starting date has 5 days difference from the previous one. Left frame: Parameters set are "Time window size" equal to 100 days and "Method of creating windows" selected to be "TIME". In this case the number of events differs in each dataset, but the time range (difference between ending and starting dates) is 100 days for all the datasets. Right frame: Parameters set are "Time window size" equal to 75 (events) and "Method of creating windows" selected to be "EVENTS". In this case the number of events the same in all dataset and equal to 100, but the time range (difference between ending and starting dates) is different for each dataset. However, when "FRONT" is selected (not shown here), nor the number of events neither the time range will be equal in the datasets.
