11.1.2 Option for codaq

A special option is to make a file used for input to CODAQ using option 18. The station name CODAQ is selcted and all stations present within the specified distance range are seleted and the output is written in file index.codaq which then contains the event-station combinations used as input to CODAQ. For componet selection, only the orientation code can be used. In addtion to to Z, N or E, also A can be used. This will select all 3 components for a selected station. In example below, all components for stations with 100 km are selected.

 CODAQ A      0    100

The CODAQ option can also be used to select events in given distance range with a given number of stations if the number of station option is also used.

Spectral paramter selection

There is no direct option to select events with spectral parameters except to select local events withe MW and assumed they have been calculated with spectra. A posibility is to use MAG where events can be output having particular spectral parameters. Another option is to use SeisanExplorer. /IndexSearch for spectral parameters
