J/\psi spin alignment study in Isobar system

 1. J/\psi isobar results for PWG meeting on April 6 2023
       Yield extraction details:
          as a  function of pT and as a function of Centrality 
 2.J\psi isobar results for PWG meeting on Aug 17 2023
      April 6 is based on a tree which did not read out all pico files due to rcf file reading issue. 
      This time we generated a new tree, and read as much pico files as we can. Also applied nsigmaE correction.
      For this two reasons, the raw J/psi yield is increased a lot. 
     This part we corrected the efficiency, but the event plane resolution correction is still under way.
3. Yield extraction check for QM Sep 2 2023
4. J/psi isobar results for HP PWG meeting on Sep 14 2023,  response to the comments
5. Preliminary request
6. J/psi isobar results at FCV PWG meeting on Sep 20 2023, the slides is the same as last weeks HP pwg meeting, response to the comments
