Notes

from Michael Dugger:

Where I am at with the 2018 polarizations: I almost have all of the 75 micron convertor files for the Spring 2018 and Fall 2018 runs. There are fewer than 100 individual files that are missing. I have run a preliminary analysis with the files available and everything looks OK. I have not encountered any unforeseen issues. I expect to have the finalized polarizations given to the collaboration within 2 weeks from now. I'll report on this during the next beamline meeting.

Take care, Michael
