**Extract stream information and time windows from an event.**
|
|
|
|
|
|
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
|
|
time window for the event to stdout. This tool gives appropriate input
|
|
information for :ref:`scart`, :ref:`fdsnws` and
|
|
`caps <https://docs.gempa.de/caps/current/apps/capstool.html>`_
|
|
(Common Acquisition Protocol Server by gempa GmbH) to dump waveforms from archives
|
|
based on event data.
|
|
|
|
Output Format
|
|
=============
|
|
|
|
The generated list contains start and end time as well as stream information.
|
|
|
|
Generic: ::
|
|
|
|
starttime;endtime;streamID
|
|
|
|
Example: ::

Examples
|
|
========
|
|
|
|
#. Get the time windows for an event in the database:
|
|
|
|
.. code-block:: sh
|
|
|
|
scevtstreams -E gfz2012abcd -d mysql://sysop:sysop@localhost/seiscomp
|
|
|
|
#. Get the asymmetric time windows for an event in an XML file. The time window
|
|
starts 120 s before the first pick and ends 500 s after the last pick:
|
|
|
|
.. code-block:: sh
|
|
|
|
scevtstreams -E gfz2012abcd -i event.xml -m 120,500
|
|
|
|
#. Create a playback of an event with a time window of 5 minutes data and sort the records by end time:
|
|
|
|
.. code-block:: sh
|
|
|
|
scevtstreams -E gfz2012abcd -d mysql://sysop:sysop@localhost/seiscomp -m 300 |\
|
|
scart -dsvE --list - ~/seiscomp/acquisition/archive > gfz2012abcd-sorted.mseed
|
|
|
|
#. Download waveforms from Arclink and import into local archive. Include all stations from the contributing networks:
|
|
|
|
.. code-block:: sh
|
|
|
|
scevtstreams -E gfz2012abcd -d mysql://sysop:sysop@localhost/seiscomp -m 300 -R --all-stations |\
|
|
scart --list - ./my-archive
|
|
|
|
#. Create lists compatible with :ref:`fdsnws` or `caps <https://docs.gempa.de/caps/current/apps/capstool.html>`_: ::
|
|
|
|
scevtstreams -E gfz2012abcd -i event.xml -m 120,500 --fdsnws
|
|
scevtstreams -E gfz2012abcd -i event.xml -m 120,500 --caps

Command-Line Options

|
Show version information.
|
|
|
|
.. option:: --config-file arg
|
|
|
|
Use alternative configuration file. When this option is
|
|
used the loading of all stages is disabled. Only the
|
|
given configuration file is parsed and used. To use
|
|
another name for the configuration create a symbolic
|
|
link of the application or copy it. Example:
|
|
scautopick \-> scautopick2.
|
|
|

.. option:: --plugins arg
|
|
|
|
Load given plugins.
|

|
|
the symlinked application.
|
|
|
|
.. option:: --shutdown-master-username arg
|
