Dear ShinIchi,


Thanks for the comments. They are implemented in the updated slides at

https://drupal.star.bnl.gov/STAR/node/54117.

p12, I agree with you. I include the one of raw data.

p15, Done. As you said, the extracted p1 and p2 of protons are the input 
values of v1 and v2.


Thank you and best regards,
