Class Description
The aim of this class is to simplify beam emittance computation done in the beam emittance measurement system. This class compute some bean optics parameters inside ESRF dipole. This class is named HardXDipoleOptic due to the two differents kind of ESRF dipole. This class is for dipole with the low magnetic field part at the dipole output (on the electron path)
