Hello Ashik,

I had mentioned in the meeting that I would cross check the cluster and point QA information with the Run 22 st_fwd production. I wasn't sure how to send it to the QA list so I was wondering if you could pass this message on to them. It seems the st_fwd and st_physics production does have the same behavior when it comes to the sigma max/min for the clusters as well as the number of points in a cluster. The number of points in a parent cluster also match. I am still investigating why this is happening since I believe it may be an error but the data from the two productions do match.

Best,

David

Hello Ashik,

I was told to contact you regarding an update on the Run 22 preproduction QA for the FCS. I have some plots now that I can show. They said there is a meeting on Fridays. Is it possible to get added to that agenda for tomorrow? If so, please send me any relevant links and meeting information.

Best,

David
