After uploading required file the User may choose any of the listed attributes (as ID, Time, Latitude etc.)

How to do:

The input file is a seismic catalog that can be uploaded from 'Change Input' tab (shown in the Image Removed of Figure 1).

Next, the User may perform various filtering according to the values of the attributes assigned in the catalog. The User may choose one of these attributes (as ID, ML, Lat etc, displayed in Figure 1 in the Image Removed )
and provide the values he/she wishes, selecting among 'Select all values' (e.g ID field, Figure 1), 'Select Range' (from the calendar - Field 1, Figure 1, or by typing values range - Field 2, Figure 1) non empty values', 'Select range' and 'Select list of values'  (Field 3 Figure 1).

depending to the attribute (Figure 2). Alternatively, the User may apply interactively spatial filtering by clicking in the "Select events from map" tab (depicted by the upper green box in Figure 5). This option grants to the User the possibility to select data, spatially constrained by a predefined shape (numbers 2-4 in Figure 6):1) click on 'SELECT EVENTS FROM MAP' button (red field in Figure 2) and do it manually as shown in figure 3.

1. No draw option.

1. Draw a polygon.The User may select data into a polygon drawn after clicking on different points of the map. To close the polygon, the User has to double click on the last point, such that this point will be connected with the first one.

1. Draw a rectangle. To select data into a rectangular the User has to click on a point of the map and move the cursor to any direction. A second left mouse button click will restrict the selected area at its current state.

1. Draw a circle (option demonstrated in Figure

1. 3). To select data into a circular the User has to click on a point of the map and move the cursor to any direction. A second left mouse button click will restrict the selected area at its current state.
   Note that the first click on the map defines the circle's center.

In any case, the User may preview the selected events after clicking on 'PREVIEW THE SELECTION ON MAP' button (green field in Figure 2).

As soon as the filtering criteria have been defined, the User shall click on the 'RUN' button to apply the those criteria. A new catalog ('catalog.mat') has been created and it is available for any further processing. In addition the system provides all the information and applications that are valid for the original catalogs (see AH Episodes).
