- Plot by each detId
- Added 2nd point's X and Y position pad
- 38 < pair E < 40 (GeV)

- Top row: default conditions have been used
   a. 20 < pair E < 40
   b. pair mass < 1.5
   c. pair zgg < 0.7
   d. Single photon clusters only
- Bottom row: cut on 2nd point's enegy as 12 < point E < 13

 - Update:
    a. Removed hotspot near x = 25, y = -20 (corresponds to detId=11, ch=210).
    b. Removed if 2nd point's position lie on [22, 26] in X and [-23, -19] in Y.
