**************************************************
I) Instructions for mmcs6500 (for LINUX ONLY !!)

To install mmcs6500 (corsika with fluka-model for low energy interaction
and QGS-JETII model for higher energy)
follow instructions. 

1)create directory fluka2011_2 (wherever you want, for instance under MagicSoft/Simulation/Corsika/Mmcs6500)

2) move fluka2011.2-linuxAA.tar.gz to directory fluka2011_2

3) go to directory fluka2011_2 and uncompress the file:

   cd fluka2011_2
   tar xvzf fluka2011.2-linuxAA.tar.gz

4) Define environment variable FLUPRO in your ~/.bashrc or ~/.cshrc. Examples:

   export FLUPRO='/home/magic/MagicSoft/Simulation/Corsika/Mmcs6500/fluka2011_2'  (bash)

   setenv FLUPRO /home/magic/MagicSoft/Simulation/Corsika/Mmcs6500/fluka2011_2     (csh)

   (then do "source ~/.bashrc"   or  "source ~/.cshrc")

   PROGRAM NEEDS FLUPRO TO WORK PROPERLY!

5) go to directory with main program mmcs6500, i.e.:

   cd MagicSoft/Simulation/Corsika/MMcs6500/

6) Uncompress qgsdat-II-03.gz :
 
   gunzip qgsdat-II-03.gz 

7) compile the program:

   make all SYSTEM=LINUX
 
8) have fun with simulations

NOTE by D. Sobczynska, about the use of CSCAT:

 *) If first value in CSCAT is lower than 21 you simulate axis core in the ring
on the plane perpendicular to the axis core. Radius between r_min to r_max.
Normally we use 

CSCAT   1      r_min       r_max              scatter Cherenkov events

which means that we are using shower only once. 
(you may use one shower no more than 20 times)

*)If first value in CSCAT is larger then 20 you simulate axis core 
 in rectangular shape ON THE GROUND.
In this case you should find core position ON THE GROUND:

- for north_south direction x between -x_max to x_max ;
- for east-west direction y between -y_max to y_max ;

CSCAT   21      x_max       y_max              scatter Cherenkov events

Line like above showes that you are using one shower only once.
You may use one shower no more then 20 times ( for 20 it looks like 

CSCAT   41      x_max       y_max              scatter Cherenkov events
