Class Description

   Parameterized Optical System
   ============================

   Parameterized optical system. This Optical System is done to reproduce the
   behaviour of an optics design through a set of parameters.
   The main pourpose is to simulate and OS with a given Triggering efficacy
   without the need of the full MC simulation.

   ParamOpticalSystem behaves as an ideal optical system with a given focal
   surface.

   The position an incoming photon hits the focal surface is calculated
   accordingly the relation

   d = (Dmax/ThetaMax)*theta

   where:
   d is the distance of the impact point on the FS from the center of the FS
   calculated along the FS.

   Dmax is the maximum distancs.

   theta is the angle between the incoming photon direction and the optical
   axis.

   ThetaMax is the maximum value of theta accepted by the optics.


   Config file parameters
   ======================

   fPos.Z [mm]: Z coordinate of the bottom base of the OpticalSystem in
   the Detector Reference System.

   fRadius [mm]: Radius of the Optical Sytem.

   fRmax [mm]: Maximmum radius of the Focal Surface.

   fDZ [mm]: Heigth of the Optical System.

   fThetaMax [deg]: Maximum valid incident angle of an incoming photon.

   fFocalSurfaceZ [mm]: Z coordinate of the center (tip) of the focal
   surface.

   fDataDirectory: path where data files are stored. If it begins with '/'
   path is assumed to be absolute, otherwise relative to this cfg file current
   position

   fTotalEfficacy.filename [string]: two column file containing the
   total efficacy as a function of the incident angle.

   fAnglesOfIncidence.filename [string]: two column file containing the chief
   ray incident angle on the focal surface as a function of the incident
   angle on the pupil.

   fPsfType [string]: type of PSF to use.
   - options
        point: No spread.
        gauss: Gaussian psf. RMS and angles of incidence listed in
               fGaussSpread.filename

   fGaussSpread.filename [string]: three column file containing RMS of the
   gaussian psf and focal surface incident photons cone aperture.
