      public BeamSizeCalculator(Optics opt, double horEmittance, double vertEmittance, double dpOp)
      Constructor with a given optics and emittances. It calculates the beam sizes along the sequence from the Twiss parameters in the optics.
      Parameters:
      opt - The optics data.
      horEmittance - The horizontal emittance.[m.rad]
      vertEmittance - The vertical emittance.[m.rad]
      dpOp - Relative momentum spread.

    • BeamSizeCalculator

      public BeamSizeCalculator(String trajectoryFile, ReferenceOrbit designOrbit, double maxAperture)
      Constructor with a given trajectory file and design orbit. It calculates the beam sizes along the sequence from the trajectory file.
      Parameters:
      trajectoryFile - The trajectory file.
      designOrbit - The design orbit.
      maxAperture - The maximum aperture. It is used for determine the observer disks radius This number is in meters.
