Meetings & Launches
- The collaboration meeting is coming up soon. Those who have been working on studies for the past few months should either give their own talk, or email Paul Mattione a few slides with their current status.
- The last analysis launch (ver05) finally finished after 1.5 months. Many files are available on the cache disk, but some may only be available on the tape. This will be the last analysis launch for a while (until the next reconstruction launch, or until there is demand).
- The simulation launch was halted because it was taking too long. Instead, it will be launched again soon with EM background disabled, with the goal of generating a dataset that is 30% of the experimental data (in events).

Channel/Physics Studies
- Alex A. presented results from analyzing rho's the 2016 Fall data, showing that the TAGM timing calibration was off (and Sean mentioned there were other issues). This has been fixed, and a new monitoring launch is planned for later this week.
- Sean mentioned that the Fall 2016 data should only be analyzed from 22016 and later, as the TOF was not calibrated before this time (HV scans, etc.)
- Also, the data showed that the rho beam asymmetry for the new diamond at low energy (3 - 6 GeV) was 3.4 +/ 0.5%, inconsistent with zero.
