Description of Low-Level Services:
...
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 (elements shown in the red box, below "INPUTS"). The User may upload any vector he/she has previously extracted from a catalog (from "change input" tab, Figure 10). This can be done with "Basic Column Extractor" Service, Column Extractor" Services, appended at the end of this Chapter. The minimum magnitude has now to be set in order to initiate the filtering process. This can be done in two ways. The first is to type a single magnitude value in the empty box. The second is to graphically select the minimum magnitude from the Normal or the Cumulative histograms, which are available after clicking on the respective tabs. In both cases there is option to alter the step of the histogram's bars and to select between linear and logarithmic scale of the Y-axis for the plotting. The User may now click on the "Run" button (blue button, Figure 10) and soon the output results are produced (shown below "OUTPUTS", in Figure 10), corresponding to the vectors of the filtered parameters.

- FilterWithinTime
...
In this Service, a certain dataset of events, characterized by Longitude, Latitude, Origin Time and Magnitude, is filtered between a minimum and a maximum time. The input for this service are four vectors with the values of the previously mentioned parameters as shown in Figure 11 (elements shown in the red box, below "INPUTS"). The User may upload any vector he/she has previously extracted from a catalog (from "change input" tab, Figure 11). This can be done with "Column Extractor" Services, appended at the end of this Chapter. The Time Range has now to be set in order to initiate the filtering process. This can be done in two ways. The first is to type a date in the empty box. The second is to select a date from the calendar appearing in the screen after clicking on the empty filed after "Start" or "End" (a calendar is depicted in the green box in Figure 11). The User may now click on the "Run" button (blue button, Figure 11) and soon the output results are produced (shown below "OUTPUTS", in Figure 11), corresponding to the vectors of the filtered parameters.
Figure 11.
- APPENDIX - Column Extractor Services
"Column Extractors" are simple tools which extract specified parameters as vectors from a given catalog. These output vectors they produced can later be used in a variety of low-level and high level services or visualization. Column Extractors can easily be applied by selecting a seismic catalog and choosing "Actions", then "Use in simple component" and finally clicking on one of the Column Extractor tools, as displayed in Figure 12 (indicated by red boxes). Then the User has just to click on the blue "run" button to extract the columns corresponding to each case. These cases are the following:
