PART 1 : DETAILS

• each root file has a tree containing these variables
• The directories where the root files produced are :

          /star/institutions/ksu/bouchet/APS/script/output-ProductionMinBias-XXX
          where XXX represents a production day

• In /star/institutions/ksu/bouchet/APS/script/scanDca/good_list/

          ,you will find the list of files (day by day)

• The total filelist is located at :

          /star/institutions/ksu/bouchet/APS/script/scanDca/good_list/test.list
          It contains 4264 root files

• In /star/institutions/ksu/bouchet/APS/script/scanDca/

          , you will find the merge root file for each day (note : it's a soft link) ; the name is rootfile_day_XXX.root

• From the total list, I splitted it into 5 lists to merge the root files

          (the macro 'add.C' seems to allow only 1000 files).
          There are located in :
          /star/institutions/ksu/bouchet/APS/script/scanDca/
          part0.list : day 98 from day 122
          part1.list : day 123 from day 141
          part2.list : day 142 to day 155
          part3.list : day 156 to day 169
          part4.list : day 170 to day 177

          The corresponding merged root files are located :
          /star/institutions/ksu/bouchet/APS/script/scanDca/
          ALL_MERGE_part0.root
          ALL_MERGE_part1.root
          ALL_MERGE_part2.root
          ALL_MERGE_part3.root
          ALL_MERGE_part4.root
