11.1.3 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
