The parameters TWLENGTH\_PLUS and TWLENGTH\_MINUS specify the length of the time window after (PLUS) and before (MINUS) the picked time. The unit is seconds. The damping factor GAMMA must be set individually.
When usig TW\_IND = 1 three columns are expected in PICK\_FILE for each trace with the picked time, time window length plus and time window length minus. In this case TWLENGTH\_PLUS and TWLENGTH\_MINUS are ignored.
When using TW\_IND = 1 three columns are expected in PICK\_FILE for each trace with the picked time (PT), time window length plus (TWLP) and time window length minus (TWLM). In this case TWLENGTH\_PLUS and TWLENGTH\_MINUS are ignored. It is also possible to use two time windows for each trace which can be utilized with TW\_IND = 2. PICK\_FILE must then contain six columns with values for PT\_1, TWLP\_1, TWLM\_1, PT\_2, TWLP\_2 and TWLM\_2 for each trace.
If you use the option "Workflow" (section \ref{sec:workflow}) it is possible to define separate files for each workflow stage. They have to be named PICKS\_FILE\_<sourcenumber>\_<workflowstage>.dat. If you don't provide separate files for some or all stages the standard file (PICKS\_FILE\_<sourcenumber>.dat) is used. This means a standard file should exist in any case.
