//!@section Source code of |creadparam.cxx|.

/*!@"
  
  This section describes briefly the source code for the file
  |creadparam.cxx|. This file is very closely related to the file
  |readparams.cxx| from the |reflector| program. Actually, this later
  file was the ancestror of the file you are looking at.

  All the defines it uses are located in the file |creadparam.h|. In
  the first one we can see the definitions of the commands available
  for the parameters file. We describe these commands in a later
  section.
  
  @"*/

//!@subsection Includes and Global variables definition.

/*!@"
  
  All the defines are located in the file {\tt creadparam.h}.

//!@subsection Definition of global variables.

/*!@"

  Here we define the global variables where the values from the
  parameters file are stored.

// This the starting point for CVS controlled further developments of the

//
// The "rootification" was done by Dirk Petry and Harald Kornmayer.

//
// ==================================================
//
// Fri Oct 22  1999   D.P.
//
// The MAGIC Monte Carlo System
//
// Camera Simulation Programme
// ---------------------------
//
// 1) Description
//
// This version is the result of the fusion of H.K.'s
// root_camera which is described below (section 2)
// and another version by D.P. which had a few additional
// useful features.
//
// The version compiles under Linux with ROOT 2.22 installed
// (variable ROOTSYS has to be set).
//
// Compile as before simply using "make" in the root_camera
// directory.
//
// All features of H.K.'s root_camera were retained.
//
// Additional features of this version are:
//
//   a) HBOOK is no longer used and all references are removed.
//
//   b) Instead of HBOOK, the user is given now the possibility of 
//      having Diagnostic data in ROOT format as a complement
//      to the ROOT Raw data.
//
//      This data is written to the file which is determined by
//      the new input parameter "diag_file" in the camera parameter
//      file.
//
//      All source code file belonging to this part have filenames
//      starting with "MDiag".
//
//      The user can read the output file using the following commands
//      in an interactive ROOT session:
//
//              root [0] .L MDiag.so
//      root [1] new TFile("diag.root");
//      root [2] new TTreeViewer("T");
//      
//      This brings up a viewer from which all variables of the
//      TTree can be accessed and histogrammed. This example
//      assumes that you have named the file "diag.root", that
//      you are using ROOT version 2.22 or later and that you have
//      the shared object library "MDiag.so" which is produced
//      by the Makefile along with the executable "camera".
//        
//  !   The contents of the so-called diag file is not yet fixed.
//  !   At the moment it is what J.C.G. used to put into the HBOOK
//  !   ntuple. In future versions the moments calculation can be
//  !   removed and the parameter list be modified correspondingly.
//
//   c) Now concatenated reflector files can be read. This is useful
//      if you have run the reflector with different parameters but
//      you want to continue the analysis with all reflector data
//      going into ONE ROOT outputfile.
//
//      The previous camera version contained a bug which made reading 
//      of two or more concatenated reflector files impossible.
//
//   d) The reflector output format was changed. It is now version
//      0.4 .
//      The change solely consists in a shortening of the flag
//      definition in the file 
//
//            include-MC/MCCphoton.hxx  
//
//  !   IF YOU WANT TO READ REFLECTOR FORMAT 0.3, you can easily
//  !   do so by recompiling camera with the previous version of
//  !   include-MC/MCCphoton.hxx.
//
//      The change was necessary for saving space and better
//      debugging. From now on, this format can be frozen.
//
//  !   For producing reflector output in the new format, you
//  !   of course have to recompile your reflector with the
//  !   new include-MC/MCCphoton.hxx .
//
//   e) A first version of the pixelization with the larger
//      outer pixels is implemented. THIS IS NOT YET FULLY
//      TESTED, but first rough tests show that it works
//      at least to a good approximation.
//
//      The present version implements the camera outline
//      with 18 "gap-pixels" and 595 pixels in total as
//      shown in 
//
//         http://sarastro.ifae.es/internal/home/hardware/camera/numbering.ps
//
//      This change involved 
//
//      (i) The file pixels.dat is no longer needed. Instead
//           the coordinates are generated by the program itself
//           (takes maybe 1 second). In the file 
//
//              pixel-coords.txt
//
//        in the same directory as this README, you find a list
//           of the coordinates generated by this new routine. It
//           has the format
//
//               number   i   j   x  y  size-factor
//
//           where i and j are J.C.G.'s so called biaxis hexagonal
//           coordinates (for internal use) and x and y are the
//           coordinates of the pixel centers in the standard camera
//           coordinate system in units of centimeters. The value
//           of "size-factor" determines the linear size of the pixel
//           relative to the central pixels. 
//
//         (ii) The magic.def file has two additional parameters
//           which give the number of central pixels and the
//           number of gap pixels
//
//         (iii) In camera.h and camera.cxx several changes were 
//           necessary, among them the introduction of several
//           new functions 
//
//      The newly suggested outline with asymmetric Winston cones
//      will be implemented in a later version.
//
//   f) phe files can no longer be read since this contradicts
//      our philosophy that the analysis should be done with other
//      programs like e.g. EVITA and not with "camera" itself.
//      This possibility was removed. 
//
//   g) ROOT is no longer invoked with an interactive interface.
//      In this way, camera can better be run as a batch program and
//      it uses less memory.
//
//   h) small changes concerning the variable "t_chan" were necessary in
//      order to avoid segmentation faults: The variable is used as an
//      index and it went sometimes outside the limits when camera
//      was reading proton data. This is because the reflector files
//      don't contain the photons in a chronological order and also
//      the timespread can be considerably longer that the foreseen
//      digitisation timespan. Please see the source code of camera.cxx
//      round about line 1090.
//
//   j) several unused variables were removed, a few warning messages
//      occur when you compile camera.cxx but these can be ignored at
//      the moment.
//
// In general the program is of course not finished. It still needs
// debugging, proper trigger simulation, simulation of the asymmetric
// version of the outer pixels, proper NSB simulation, adaption of
// the diag "ntuple" contents to our need and others small improvements.
//
// In the directory rfl-files there is now a file in reflector format 0.4
// containing a single event produced by the starfiled adder. It has
// a duration of 30 ns and represents the region around the Crab Nebula.
// Using the enclosed input parameter file, camera should process this
// file without problems.
//
// 2) The README for the previous version of root_camera
//
// README for a preliminary version of the 
// root_camera program. 
//
// root_camera is based on the program "camera"of Jose Carlos
// Gonzalez. It was changed in the way that only the pixelisation 
// and the distibution of the phe to the FADCs works in a 
// first version. 
//
// Using the #undef command most possibilities of the orignal 
// program are switched of. 
//
// The new parts are signed by 
//
// - ROOT or __ROOT__ 
//   nearly all  important codelines for ROOT output are enclosed 
//   in structures like 
//   #ifdef __ROOT__ 
//   
//     code 
//
//   #endif __ROOT__ 
//
//   In same case the new lines are signed by a comment with the word 
//   ROOT in it. 
//
//   For timing of the pulse some variable names are changed. 
//   (t0, t1, t  -->  t_ini, t_fin, t_1st, t_chan,...) 
//   Look also for this changes. 
//
//   For the new root-file is also a change in readparm-files
//
//
// - __DETAIL_TRIGGER__
//
//   This is for the implementation of the current work on trigger 
//   studies. Because the class MTrigger is not well documented it 
//   isn´t a part of this tar file. Only a dummy File exists. 
//
//
//
// With all files in the archive, the root_camera program should run. 
//
// A reflector file is in the directory rfl-files
//
// ==================================================
//
// From now on, use CVS for development!!!!
