• 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
