<span id="concepts-locators"></span><h1>Locators<a class="headerlink" href="#locators" title="Permalink to this heading">¶</a></h1>
|
|
<p>Locators receive <a class="reference internal" href="../glossary.html#term-pick"><span class="xref std std-term">phase picks</span></a> from modules such as <a class="reference internal" href="../../apps/scautoloc.html#scautoloc"><span class="std std-ref">scautoloc</span></a>,
|
|
<a class="reference internal" href="../../apps/screloc.html#screloc"><span class="std std-ref">screloc</span></a> or <a class="reference internal" href="../../apps/scolv.html#scolv"><span class="std std-ref">scolv</span></a> for locating seismic or non-seismic sources. The
|
|
solutions may include source time and location with or without uncertainties.
|
|
They are used to form new <a class="reference internal" href="../glossary.html#term-origin"><span class="xref std std-term">origins</span></a> which can be treated
|
|
further.</p>
|
|
<p><cite>SeisComP</cite> ships with built-in locators:</p>
|
|
<ul class="simple">
|
|
<li><p><a class="reference internal" href="../../apps/global_fixedhypocenter.html#global-fixedhypocenter"><span class="std std-ref">FixedHypocenter</span></a> (FH)</p></li>
|
|
<li><p><a class="reference internal" href="../../apps/global_hypo71.html#global-hypo71"><span class="std std-ref">Hypo71</span></a></p></li>
|
|
<li><p><a class="reference internal" href="../../apps/global_iloc.html#global-iloc"><span class="std std-ref">iLoc</span></a></p></li>
|
|
<li><p><a class="reference internal" href="../../apps/global_locsat.html#global-locsat"><span class="std std-ref">LOCSAT</span></a>, the default locator in <a class="reference internal" href="../../apps/scautoloc.html#scautoloc"><span class="std std-ref">scautoloc</span></a> and <a class="reference internal" href="../../apps/scolv.html#scolv"><span class="std std-ref">scolv</span></a></p></li>
|
|
<li><p><a class="reference internal" href="../../apps/global_nonlinloc.html#global-nonlinloc"><span class="std std-ref">NonLinLoc</span></a></p></li>
|
|
<li><p><a class="reference internal" href="../../apps/global_stdloc.html#global-stdloc"><span class="std std-ref">StdLoc</span></a></p></li>
|
|
</ul>
|
|
<p>and a none built-in locator:</p>
|
|
<ul class="simple">
|
|
<li><p><a class="reference internal" href="../../apps/global_locext.html#global-locext"><span class="std std-ref">LocExt</span></a>.</p></li>
|
|
</ul>
|
|
<p>While the built-in locators are well defined and documented, any other external
|
|
locator routine can be added to <cite>SeisComP</cite> by configuration of the locator
|
|
<a class="reference internal" href="../../apps/global_locext.html#global-locext"><span class="std std-ref">LocExt</span></a> and custom scripts.
|
|
LOCSAT and FixedHypocenter are native to <cite>SeisComP</cite>. All other locators are
|
|
implemented as <a class="reference internal" href="../glossary.html#term-plugin"><span class="xref std std-term">plugins</span></a>. A <a class="reference internal" href="../glossary.html#term-plugin"><span class="xref std std-term">plugin</span></a>
|
|
needs to be added to the list of loaded plugins by configuration of the global
|
|
parameter <a class="reference internal" href="../../apps/global.html#confval-plugins"><code class="xref std std-confval docutils literal notranslate"><span class="pre">plugins</span></code></a> for making the corresponding locator available to
|
|
<cite>SeisComP</cite> applications.</p>
|
|
<p>A comparison of the locators is given in the table below.</p>
|
|
<div class="admonition note">
|
|
<p class="admonition-title">Note</p>
|
|
<p>The specifications given below may depend on the configuration of the

respective locator. Please carefully read the documentation of the locators

for optimizing their performance.</p>
