STAR QA Board

[videbaek <videbaek@bnl.gov>]

Hi just a comment to the excessive hits in a few rdo's 2021-12-24 13:17,
These excess hist are all with flag==1; these are NOT used in tracking, 
but
their presence likely affect the real hits since they occupy ~20% of 
pads in

One option would be to mask out the RDO (in DB) and then they would be 
dealt with properly in offline and embedding.
