Hello Rongrong,

   I usually use this command to get the file list: find 
/star/data[01][0129]/reco/production_pp500_2022/ReversedFullField/dev/2022/ 
-type f -name "st_physics_*.picoDst.root", this command will find all the 
st_physics* for production_pp500_2022 in path /star/data09-12, if there is 
any other path I missed, please kindly let me know, and I also update the 
file list on Sunday, and the run 23066068 is still an empty run, and checked 
the <refmult> for run 23069015, it seems normal, also using the shifted 
|Vz-VpdVz| to get the new Vz distribution, and please find the specific plots 
in this link: 
https://drupal.star.bnl.gov/STAR/system/files/20220311_pp_500GeV_Mtd_Vz_check_v2.pdf

Best regards,
Kaifeng
