During each pass change, we require a spectrometer pointing survey for the Left HRS and sometimes for the Right HRS.

  • LHRS: θ = 42.0o (after first pass optics)
  • RHRS: θ = 48.75o (after first pass optics)
  • LHRS: θ = 30.9o (after fourth pass production)
  • RHRS: θ = 55.5o (after fourth pass production)
  • LHRS: θ = 44.5o (after third pass production)
  • RHRS: θ = 48.75o (after third pass DVCS elastic calibration)
