10.2 Option for codaq

A special option is to make a file used for input to CODAQ. 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.

 STAT CO Mindis Maxdis Phas All stat hdist->FF
 CODAQ A      0    100

- Polygon
Selects events within a given polygon of at least 3 latitude-longitude pairs. - Use all header lines
All header lines are searched for relevant information - Look for waveform file names
Search the database for particular waveform files, input can use a fraction of file name or * for any name. No wildcards can be used in the string so e.g. ASK* will select all due to the *. Use just ASK in this case to select all filenames with the string ASK. - Gap range
The range of gap as given on the E-line (normally 2. header line). Only hypocenters calculated with SEISAN version 7.0 have gap. - Phase
Look for events with particular phases. Up to 6, 4 character phase names can be selected. The event is selected if at least one of the phases is present for the event. For a more selective selection based on phase, see option 18. - Volcanic subclasses
Search for events of given subclasses given by up to 10 codes. Any code can be given, however, normally they will be as defined in VOLCANO.DEF. The program searches for lines starting with `VOLC MAIN'.

Historical data: When working with historical data, it can be useful to work with catalogs of several centuries. The century is available in the Nordic Format, so catalogs can go back to year 0. Output:

select.out: A CAT-file or compact file (depending on input) of selected events.

index.out: A list of event id's of selected events can be used with EEV or other programs accepting index files. This could be used e.g. to work on only distant events in the database by first selecting all distant events and then working with these directly in the database using command EEV index.out. Index files can have any name (must contain a `.') so different subsets can be available with different index files.

Waveform_names.out: A list of corresponding waveform files. It is mainly intended for copying to or from tape specific waveform files. It has the format of the filenr.lis files and can be used directly with e.g. MULPLT. See also program get_wav for selecting waveform files from the database.

select.inp: A file with all the parameters used for the run. The file can be renamed, edited and used as input for select. This is particularly an advantage if a complex set of selection parameters are used and the selection is wanted again with just a small change. An example file is shown below
