I noted a problem (or rather feature) in runs 5693, 5694, 5695, and 5695 which contains about 1/3 the statistics of the 90 deg 350A
pol. Adding all the runs I saw time shifting around.
There is a simple explanation for this these set of runs are 'different gains runs on the BB so they have to be calibrated individually
and a new cal needs to be done for 5701

This was of course the set of runs for which I was checking the validity of the MRS slewing.
with all the 5361 and up runs done for tracking this should go fast(er)
