Review of minutes from the January 16 meeting

We went over the minutes. Mark will contact Paul Eugenio about his plans, if any, for a talk at the Collaboration meeting.

Calibration Status

Still done.

Lucite Shield Geometry

Since the last Software Meeting, Richard has added the shield to HDDS in the CCDB for both DIRC and non-DIRC runs. See his message from January 23.

Ashley finds that the version checked in has the inner box too long (9 cm rather than 2.5 cm). She has suggested the correction to Richard.

We agreed that we probably should have a build of the HDDS suitable for non-DIRC runs available as a public build, notwithstanding discussion to the contrary at yesterday's HDGeant4 meeting.

Upgrade Plan

No new news.
