1) To test brems sampling and compare it with the brems function,
	make clean
       ./testBremSamp.sh  media events E1 E2 step [LPMeffect Flpm logx func]
 where
	media: such as Fe BGO Air Air*0.1
	events: # of events (samplings) for each energy
	E1 E2: kinetic energy of electron; form E1 to at least E2
	step:  log10 step of energy
	LPMeffec: t or f for LPM effect; default is t
  For more details, use the command without arguments.
        ./testBremSamp.sh 

   You can see gnuplot display for each energy.  The y-axis is prog/r.l 
	 To see next graph,   click the window.
	 To make it slide show, you may modify
	  brems.gp:(pause mouse => pause 2 etc )
   The command also save png figures in Work/ as brems1.png etc.
   The size may be changed by modifying brems.gp (see it's last part).

2) To test pair sampling and compare it with the pair funtion,
	make clean
        ./testPairSamp.sh  media events E1 E2 step [LPMeffect func]
 where
	media: such as Fe BGO Air ...
	events: # of events (samplings) for ehac energy
	E1 E2: kinetic energy of electron; form E1 to at least E2
	step:  log10 step of energy
	LPMeffect: t or f for LPM effect; default is t
	func:  Pair func by Tsai-->1; by Nelson-->2(default is 2)
   Others are the same as brems case.

3)  To draw brems functions for different energies in a page,
        ./showBremFunc.sh  media func how E1 E2 step [norm
           LPMeffect Flpm logx xmin linew linet ]
    For details, use the command without arguments.

4)  To draw pair functions for different energies in a page,
    ./showPairFunc.sh  media  E1 E2 step [norm func]
    For details, use the command without arguments.

5) To create a sampling table for a given medium;
	The basic media file such as Epics/Data/BaseM/Pb
	must be prepared.
	Then,
	make clean
	./CreateTab basic_media_table output_table_dir
 where
	basic_media_table: such as ../../../Data/BaseM/Pb
	output_table_dir:  such as ../../../Data/Media
  To test the result, use 1) and 2).

6) To make a sampling table for a given  media without
   vervose mode (i.e, use only defautl values).
	make clean
	./AutoCreateTab basic_media_table output_table_dir
7) To make a sampling talbe for all media in some directory
	do e.g,
	make clean
	bash (if your shell is not bash)

        ./AutoCreateTab.sh  dir  

         dir:   ouput directory such as /tmp/$USER/Media
