     *  @history 1998-12-21 Randy Kirk - USGS, Flagstaff - Original
     *          code.
     *  @history 2007-02-20 Janet Barrett - Imported from Isis2.
     *  @history 2007-08-15 Steven Lambright - Refactored code
     *  @history 2008-03-07 Janet Barrett - Moved code to set standard
     *                          conditions to the AtmosModel class
     *  @history 2008-06-18 Christopher Austin - Fixed documentation error
     *  @history 2008-11-05 Jeannie Walldren - Replaced reference to
     *                          NumericalMethods::r8expint() with AtmosModel::En().
     *                          Added documentation from Isis2.
     *  @history 2011-08-17 Sharmila Prasad - Moved common HNORM to base AtmosModel
     *  @history 2011-12-19 Janet Barrett - Added code to estimate the
     *                          shadow brightness value (transs). Also got rid of
     *                          unnecessary check for identical photometric angle values
     *                          between successive calls. This check should only be
     *                          made in the photometric models.
     *  @history 2017-07-03 Makayla Shepherd - Updated documentation. References #4807.
