8.2 Use of MULPLT from EEV and SE

In order to process events more easily, EEV and SE and MULPLT have been tightly integrated. When MULPLT is called from EEV or SE, command f will plot the next event in the database, to go back to the same event in EEV, use quit. The event can be plotted with default parameters from EEV using PO. If PO has been selected, the f command in MULPLT multi trace mode will show the plot of the next event with default options. This is a fast way of plotting waveform files going through S-files in a database. The command poo does the same as po except that you start in single trace mode. In SE, command P corresponds to PO in EEV.

If several waveform files are available, the user will graphically be shown the files and can select one or several Files can optionally be displayed in alphabetical order (see MULPLT.DEF). If more than 75 files, several selection screens will be shown. A maximum of 1000 files can be used if the PO option has been used, all default channels will be used.

Plotting from EEV or SE, a file with a list of waveform files can also be used as input. The filename must end with _LIST. The filename could be e.g. 2002-02-02-1310-20S.BER_LIST. The format is the filenr.lis format so the file can be created with DIRF. The _LIST file can be in local directory, WAV or any other directory as specified for normal waveform files. The intention with the list option is to be able group many waveform files in one group without the need to merge the files or list them all in the S-file. The limit of number of files in the _LIST files is 1000 and up to 10 _LIST files can be used for the same event. There is currently no automated facility to create and include _LIST files in the S-file.

Components: The picks in the S-file are plotted on respective traces if both the station name and component matches. The waveform file has in general a 3 letter component code. Nordic2 also has 3 letter component code while the old Nordic format S-file only has 2 so here only the first and last letters are checked for matching. Similarly, when writing a pick to the S-file, in Nordic2 all 3 are writen to the S-file, but in old Nordic only first and 3. letters are used. In case there are no compoenet code in S-file, the readings in the S-file are shown on all componenets. If any subsquent readigs are done, the component code of the first channel used will be assigned to all readings for that station.
