This Application is performed in order to transform the epicentral location of the seismic events into a selected Cartesian Coordinate System (Note that epicentral location data available in IS-EPOS is given in geographical coordinates). The available types of coordinate systems are shown in Figure 7 (KOSTAS: maybe a short description of those systems is needed here). Once the User makes the selection and clicks on the "Run" button, a new catalog is created, which contains all the data previously available in the original catalog, plus the seismic events epicentral location in the selected Cartesian system. The new catalog is stored in the platform and is available for any further processing. In addition IS-EPOS provides all the information and services that are valid for the original catalogs (see "AH Episodes" Chapter, for details).

•  A report with the parameters (slope and intercept) of the regression process and some associated statistical parameters (Figure 8)
• Vectors of the first, second magnitude selected, together with the vector of the new (converted) magnitudes obtained by the application of the regression equation.
• A figure with one magnitude scale plotted versus the other one (scatter plot) and the linear regression curve (Figure 9). Zooming option is enabled for this Figure.

In this Service, a certain dataset of events, characterized by Longitude, Latitude, Origin Time and Magnitude, is filtered over a minimum magnitude (i.e. completeness level). The input for this service are four vectors with the values of the previously mentioned parameters as shown in Figure 10.
