Dear Annalisa,

Here are the timelines, along with some notes:

https://clas12mon.jlab.org/dilks/rgk_test/timeline/

-- beam spin asymmetry
- pi+ beam spin asymmetry has the wrong sign, likely because RGK helicity
   assignment is opposite what RGA and RGB use; it's simple to fix and 
can be
   done later when reading pass1 data. It is also interesting to note 
that the
   magnitude of the pi+ asymmetry is around 4% for RGK, but for RGA and 
RGB it
   is 2%.

-- electron trigger yield normalized values
- the four runs have a wide range of FC-normalized electron trigger yields;
   therefore the QA cuts are defined separately for each run. These 
normalized
   yields are nearly constant within each of the runs, except for the 
first file of run
   5958 (but that's perfectly normal, sometimes the first or last file 
of a run does this)

All the other timelines look normal, but there is a jump in the pion pT 
between 5823 and 5893, as well as x and Q2

I've also attached some slides which describe how the QA works, but they 
are a bit out of date; in particular, an issue regarding the livetime 
was fixed, so there's no longer a need for a livetime>1 defect bit.
