Here are my results of calibrating the EPD over days 52-58 of run21. This week was not well behaved at all, with a few tiles changing from day to day. Some changes in the working of the EPD also happened, specifically on days 54 and 55.  This split the days into two halves, essentially. With this blog are the files for entry into the database with a supplementary timestamps file for the split days, all enclosed in a zip file.
