Review of minutes from the last meeting

We reviewed the minutes from the meeting on July 2. See the entry for Issue #109 below for the discussion.

HDGeant4 and the Time-of-Flight Upgrade

Sean has noticed that there are a few geometry parameters for the TOF in HDGeant4 that have hard-wired values. These should come from the HDDS files served by the CCDB. Richard agreed to have a look.

[Added in press: Sean created Issue #123 after (during?) the meeting].

DIRC simulations

See the entry for Issue #121 below for discussion on this topic.

Tracking Efficiency Study

We reviewed the plots that Naomi sent to Mark. These have been shown at a previous tracking meeting. See Naomi's slides for the details. We looked at the plots near the end. They show good overall agreement between efficiency for pions and protons over a wide kinematic region when comparing HDG3, HDG4, and real data.

Issues on GitHub

We reviewed the issues.
