== September 18 2019 ==

'''Daily Meeting [https://bluejeans.com/454783784 BlueJeans]'''

== Data ==
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 ==

== Issues ==
* 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 ==
=== Pedestals ===
* 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

== Attendance ==
Cameron, Tao, Victoria, Devi, Adam, Eric, Weibin, Ryan, Sakib, Robert, Paul King
