MAXIV_Bloch InstrumentThis is a simple simulation of the BLOCH beamline at MAXIV. Two kinds of parameters are given, P and P2. P Parameters are the ones used in the general simulation, i.e when the FOI is intensity ect. P2 parameters are used when the strain of the beamline is the FOI, i.e what happens when the distances change.
