STAR Correlations and Fluctuations PWG

[Rongrong Ma <marr AT rcf.rhic.bnl.gov>]

Dear All

The latest StRefMultCorr class with Run19 19.6 GeV centrality definition has 
now been merged into the main branch, and is available on RCF in DEV 
(/afs/rhic.bnl.gov/star/packages/DEV/StRoot/StRefMultCorr). 

IMPORTANT: please pay close attention to the example code provided by Grigory 
(/star/u/gnigmat/soft/u/refMultCorr/checkStRefMultCorr.C). In particular, 
users need to call functions in StRefMultCorr to check bad run and reject 
pileup events in their own codes. We will work on automating these checks 
within the StRefMultCorr class after QM. 

Thanks. 

Best
Rongrong
