	 ( -o [output root name] ) \
	 ( -H [output histogram name] ) \
	 ( -v ) \

 -o : if it is not given, out put file name will be "syst.root"
 -H : if it is not given, the output histogram name will be the same as [histogram_name in rootfile_new_nominal]
 -v : verbose output mode. no effect to the result.


Tips 1 :
 If you have the three histograms in one file, you only need one "-i".
 e.g. ./main -i xxx -h h1 -h h2 -h h3 
 

Tips 2 :
 If you use the same name for all the three histograms in each file, you only need one "-h".
 e.g. ./main -i f1 -i f2 -i f3 -h xxx
