Setting the Calorimeter angle (SMHS carriage):
- NPS Survey Results
- SHMS angle (as defined in magnet gui) = Desired Calo Angle + Offset
- Average offset 16.289 deg.
- To set SHMS angle, use universal offset 16.27 deg. Corrections can be made in analysis
- Setting the SHMS to angles less than 28 deg (NPS < 11.7 deg) requires tech support and two people in the hall
| Calo Distance | SHMS Offset |
| 3.0 m | 16.3068 deg |
| 4.0 m | 16.2782 deg |
| 6.0 m | 16.3010 deg |
| 8.0 m | 16.2718 deg |
