Description
|
||||
===========
|
||||
|
||||
scevtstreams reads all picks of an event and determines the time window between
|
||||
the first pick and the last pick. In addition a symmetric or an asymmetric time
|
||||
margin is added to this
|
||||
time window. It writes the streams that are picked including the determined
|
||||
scevtstreams reads all picks of an event or solitary picks determining the time
|
||||
window between the first pick and the last pick.
|
||||
In addition symmetric asymmetric time margins are added to this time window.
|
||||
It writes the streams that are picked including the determined
|
||||
time window for the event to stdout. This tool gives appropriate input
|
||||
information for :ref:`scart`, :ref:`fdsnws` and :cite:t:`capstool` for
|
||||
:cite:t:`caps` server (Common Acquisition Protocol Server by gempa GmbH) to dump
|
||||
waveforms from archives based on event data.
|
||||
|
||||
Events with origins and picks can be read from database or XML file. Solitary
|
||||
picks can only be read from XML file. The XML files can be generated using
|
||||
:ref:`scxmldump`.
