+/*! \class JetTable
+    \brief STK jet table class.
+
+    This class implements a flue jet non-linear
+    function, computed by a polynomial calculation.
+    Contrary to the name, this is not a "table".

+    Consult Fletcher and Rossing, Karjalainen,
+    Cook, and others for more information.
