September 18 2019

Daily Meeting BlueJeans


We want to look at all of the data and figure out what changes need to be done to get ready for respin/final results (idealistically)

Pedestal/Calibrations Updates


  • Slug 7 needs to be changed to correctly reflect IHWP setting
  • Dithering sensitivity changes/other kinds of changes should not be considered as slug changes

Slug 0 Inclusion

  • Slug 0 was marked as suspicious at the time

Slugs 1-3 Inclusion

  • Because of different BPM DAQ inclusion we haven't been using these slugs in our aggregation
  • An aggregator hack can be done or we can just have the plots be empty

Slug 7 update

  • Prior slug 6 was ~50 uA, and OUT
  • Slug 7 is basically a parity scan
  • Goal is to take the tail of "slug 7" as it was originally taken and make it part of slug 6
    • Take 3444-3446 as IN, slug 7
    • Take 3447-3452 and put them in OUT slug 6 (because slug 8 is basically left arm only... hard to merge in)

Slug 13-18 slugs inclusion

  • Devi has included data from some of his slugs into the lists that were previously not there (will show up in respin)

Single/Both arm slugs ???

  • Slug 43 has 4 runs with only one arm
  • Slug 74 has several runs with only one arm

To resolve these:

  • Could make the aggregation scripts check the arm variable in order to make plots correctly
  • Could do add + 100 for right only, + 200 for left only

Lets add BMOD Active Data back into our "good" data cut

  • We need to identify exactly what the JAPAN decoding -> BMOD-on flagging mechanism is, and maybe pass off this flag to another place
  • We need to verify that this is OK with plots and stuff
    • Original data set
    • Only BMOD on data set
    • Both together data set
    • If anythin crazy happens then this needs further investigation
  • This requires amending the error flag cuts everywhere to show BMOD in the "good" data

Planned Updates


  • We should look at all of the calibration runs/condition changes and make sure that the pedestals calculated accurately reflect the conditions during that time
  • We should make sure that all pedestal changes are well motivated and no calibration runs were neglected
  • We should make sure that early runs aren't missing pedestals that may currently have later run ranges (Due to late application)

Slug perfection

  • Everyone should look through at least their slugs and address any suspicious runs or runs needing additional cuts
  • Don't be afraid to make the change directly if it is safe, and be sure to commit to the operations branch
  • If there is something that needs more attention (especially slug / run reassignment) please bring it up either by email to the WAC group or to the next WAC meeting
