<p>Module defining the generator determinants as those belonging to a <abbr title="Complete Active Space">CAS</abbr>.
The <abbr title="Molecular Orbitals">MOs</abbr> belonging to the <abbr title="Complete Active Space">CAS</abbr> are those which were set as active with
the <a class="reference internal" href="../users_guide/qp_set_mo_class.html#qp-set-mo-class"><span class="std std-ref">qp_set_mo_class</span></a> command.</p>
<p>This module is intended to be included in the <code class="file docutils literal notranslate"><span class="pre">NEED</span></code> file to define
the generators as the <abbr title="Complete Active Space">CAS</abbr> determinants, which can be useful to define post-CAS approaches (see cassd module for instance).</p>
