  1. Tao
    • beam mod data quality plots [weblink]
    • Corrections summary plots [weblink] : regression / combo BPM regression / dithering
    • grand statistics preview [HAPLOG 4043]
    • KP: slug 0 may not have Aq feedback running. CG: not sure how much we can recover from large Aq.
    • CG: double check with Weibin about event cuts
    • KP: Not sure why we are doing blinder in this way for single arm. PK: this is how we do it during summer
    • Checklist / to-do list
      • Are plots/summary text files properly uploaded to the webpage? Any rootfiles missing ? (Robert)
      • Review beam mod data : run ranges for averaging slopes, bad supercycle cuts , residual sensitivity and etc. (Victoria)
      • review event cuts/ mapfiles / data (Weibin / Tao / Robert)
      • keep track of issues : [HAPLOG 4044]
  2. Devi
    • Missing plots on the webpage; Already spoke to Robert.
    • AT detectors data issue: outlier from blinding failure and we need device error code cut.
    • PK: Assume the regression slope are ok, cut on device_error_code on AT detectors.
    • KP: We need to look at AT now and see if it is correlated with other systematics.
    • PK: try to look at JAPAN regression which has AT device error code included. KP: if so, lets use regression slope from JAPAN LRB
    • KP: do we have kinematic information about ATs? We need to review them.
    • RyR: if you have a counting run list, I can look at it. Devi/Dustin: we can have a google sheet.
    • KP: do we have dithering on ATs with device error code. KP: combiner summary tree have device error code included from each elements.
