 Define a computation that calculates properties of individual dihedral
 interactions.  The number of datums generated, aggregated across all
-processors, equals the number of angles in the system, modified by the
-group parameter as explained below.

 The value {phi} is the dihedral angle, as defined in the diagram on
 the "dihedral_style"_dihedral_style.html doc page.
