Tool for downloading signals connected to events selected from a  Catalog ,  Ground Motion Catalog  or  GM Parameters Catalog . Signals might be further converted by  Seed or miniSEED Converter applicationapplications  or directly processed by other applications (e.g.  Source Parameter Estimation applications ). Additionally, the application returns event information ( Seismic event ) for each selected event.

Step by Step

This applications extracts seed files and event files from a selected catalog into the User workspace. These extracted files can be used later on at any application dealing with waveform processing, including 'Spectral Analysis', 'Source Location', 'Moment Tensor Inversion' and 'Seed converter'. This

The application uses catalog file (uploaded from the episode data) as an input and allows the User to extract seed, miniSEED and event files. This is an alternative way of exporting seed files instead of searching into the episode database.

The User needs first to select a catalog from the workspace and click subsequently on 'ACTIONS', 'USE IN APPLICATION' and

 From the 'Actions' tab within the Catalog file view, the User may select 'Use in Application' option and then choose 'Signal download tool'

tabs, as indicated by the red boxes in Figure

2. After this step, the list of events appears in the screen as shown in Figure 2 and the User is requested to select an event for extracting event information and seed file. The User may also chose downloading

events from catalog.

Then, the User may chose which signal types to download between 'Seed Signal', 'Accelerogram Seed Signal', Miniseed Signal' or 'All', by ticking on the respective box shown

at the bottom left corner of Figure 2. Then, the output files are extracted after clicking on the Image Removedbutton (green button, bottom Figure 2). Those files are stored in a Signal Download folder, into the User's workspace and

in green filed in Figure 1.

Output files can be further used as input in several applications

as mentioned above.
