- The track-finding efficiency study will be repeated with the latest snapshot, which includes updates to the KF strategies and some bug-fixes. Norman Graf
- 05/12/21: The sample was re-reconstructed using the latest merge of the kalman_dev branch into hps-java master.
- The SeedTracker/GBL result stayed the same, at 14.3% overall "inefficiency"
- The Kalman Filter result worsened slightly to 16.4% overall "inefficiency"
- The dependence of the "inefficiency" on cluster Esum perhaps reflects larger non e- gamma backgrounds at low Esum

- The study will be expanded to investigate the efficiencies as a function top/bottom, momentum, etc. Norman Graf
- A standalone Driver will be written to draw the SVT sensor geometries to enable easier inspection of their positions. Norman Graf
- Instructions will be posted on how to use the Wired4 event display. Norman Graf
- A formal presentation on the DQM will be scheduled for two weeks hence. Mathew Graham
- Omar will contact Jeremy to revisit the project where DQM plots had been made available on the web. Omar Moreno
- After discussions at the 5/12/21 HPS weekly meeting it was decided that remote shifters should connect directly via VNC, so this will be shelved.
