- Update in Mar. 27:
   a. Replace plot to the one including all region of zgg
   b. Add plot in unified scale

- Tested effect of zgg on mass vs. pair E distributions
- This splitting behavior happens independent of zgg, but only in small cells
- Only detId = 8 and detId = 10 will be shown (8 and 9, 10 and 11 are look almost same)

 //------------------------------------------------------------------------------

- detId  = 10

  a-1. Separated by zgg in stepwidth of 0.1 (ex. 0.1 < zgg < 0.2), from 0.1 - 0.7

 


  a-2. Separated by zgg in stepwidth of 0.1 (ex. 0.1 < zgg < 0.2), from 0.1 - 0.7, in same z scale

  b-1. Incremental zgg (ex. < 0.1, < 0.2, ... from < 0.1 to < 0.7 )

   b - 2. Incremental zgg (ex. < 0.1, < 0.2, ... from < 0.1 to < 0.7 ), in same z scale

 //------------------------------------------------------------------------------

- detId = 8

  a. Separated by zgg in stepwidth of 0.1 (ex. 0.1 < zgg < 0.2), from 0.1 - 0.6

  b. Incremental zgg (ex. < 0.1, < 0.2, ... from < 0.2 to < 0.7 )
