Possible sequence and times
- CPP test DAQ setup: 2 hrs
- Repeat measurement with nominal GlueX configuration: 2 hrs
- Configure experiment for CPP Test: 12 hours max
- Start with no DIRC, no shielding
- Take data: 2 hours
- Install Pb shielding: 2 hours
- Take data: 2 hours
- Install 2 Pb shields: 2 hours
- Take data: 2 hours
