This is an application for filtering seismic catalogs. The product is a new catalog filtered upon the User's parameters setting.
How to do:
The input file is a seismic catalog that can be uploaded from 'Change Input' tab (shown in the 
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) 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 1, Figure 1) and 'Select list of values' (Field 3 Figure 1).

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) No draw option.
2) 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.
3) 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.
4) Draw a circle (option demonstrated in Figure 6). 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.
