  The following set of flags are used in time of compilation. They do
  not affect directly the behaviour of the program at run-time
  (though, of course, if you disconnected the option for
  implementation of the Trigger logic, you will not be able to use any
  trigger at all. The 'default' values mean default in the sense of
  what you got from the server when you obtained this program.

//!@subsection Definition of global variables.

/*!@"

  Now we define some global variables with data about the telescope, 
  such as "focal distance",  number of pixels/mirrors, 
  "size of the camera", and so on.

  @"*/

/*!@"

  Depending on the telescope we are using (CT1 or MAGIC), the 
  information stored in the definition file is different.
  The variable |ct_Type| has the value 0 when we use
  CT1, and 1 when we use MAGIC.

  @"*/

  And this is the information about the whole telescope.

// Revision 1.5  2000/02/18 17:40:35  petry
// This version includes drastic changes compared to camera.cxx 1.4.
// It is not yet finished and not immediately useful because the
// trigger simulation is not yet re-implemented. I had to take it
// out together with some other stuff in order to tidy the whole
// program up. This is not meant as an insult to anyone. I needed
// to do this in order to be able to work on it.
//
// This version has been put in the repository in order to be
// able to share the further development with others.
//
// If you need something working, wait or take an earlier one.
// See file README.
//
// Revision 1.4  2000/01/25 08:36:23  petry
// The pixelization in previous versions was buggy.
// This is the first version with a correct pixelization.
//
// Revision 1.3  2000/01/20 18:22:17  petry
// Found little bug which makes camera crash if it finds a photon
// of invalid wavelength. This bug is now fixed and the range

// This is in preparation for the NSB simulation to come.
