Integrate array parameters in |scname|
======================================

Manual Analysis
---------------

Picks and origins received from the messaging system can be interactively
processed e.g. by :cite:t:`scolv`:

#. Use the Cart window in |vappname| to:

   #. collect array detections: picks with time, slowness, backazimuth or
      origins from the one or from multiple arrays,
   #. identify detections from the same seismic event,
   #. relocate to form a new origin,
   #. commit origins to the |scname| messaging.

   or provide origins and picks by |appname|.

#. Use :cite:t:`scolv` to either

   * add the picks to other existing or artifical origins,
   * process arrays origin adding more picks from other origins,
   * relocate, compute magnitudes, etc.

In the arrival table and the picker window of scolv, beam picks from array
processing are identified by the method:

* **A<B>**: automatic pick from beampacking,
* **A<F>**: automatic pick from F-K analysis.

Time, slowness and backazimuth may be selected individually in the arrival table
for locating.

Automatic Processing
--------------------

When connected to the |scname| messaging |appname| and |vappname| will send the
results as picks and origins to message groups from where they can be received
and automatically processed by other modules:

* Picks are sent to the primary group defined by the global parameter
  :confval:`connection.primaryGroup`,
* Origins along with their arrivals are sent to the location group defined
  |appname| or |vappname| parameter in :confval:`connection.locationGroup`.
  The associated picks are sent to :confval:`connection.primaryGroup`.

In a :cite:t:`pipeline` setup with modified message groups,
:confval:`connection.primaryGroup` and :confval:`connection.locationGroup` should be
configured accordingly.


Picks
~~~~~

Picks can be received by modules like :cite:t:`scanloc` or :cite:t:`scautoloc`
for further processing to form new origins or to add to existing origins.

Picks from array processing usually have a pick time along with slowness or
backazimuth or all parameters. Depending on the accuracy and on the locator
backazimuth and slowness may bias hypocenter solutions. Consider activating or
deactivating these parameters for the considered locator. For :cite:t:`locsat`
configure the global parameters :confval:`LOCSAT.usePickBackazimuth` and
:confval:`LOCSAT.usePickSlowness`.


Origins
~~~~~~~

Origins e.g. from backprojection can be received by :cite:t:`scanloc` for
associating more P and S phases. Configure scanloc accordingly to start
associating even when an origin has only one arrival. Consider initial hypocenter
uncertainty.
