class ocelot.cpbd.response_matrix.MeasureResponseMatrix(lattice, hcors, vcors, bpms)
calculate(self)
read_virtual_orbit(self, p_init=None, write2bpms=True)

searching closed orbit by function closed_orbit(lattice) and searching coordinates of beam at the bpm positions

Parameters

lattice – class MagneticLattice

Returns

orbit.bpms

read_virtual_dispersion(self, E0)
optical_func_params(self, tw_init=None)

Optical function parameters for correctors and bpms. It is needed for calculation of ideal response matrix: defining beta functions on the azimuth of correctors and bpms: beta_x, beta_y; defining phase shift between origin of lattice and element: mu_x, mu_y; defining tunes of beta functions of whole lattice: nu_x, nu_y = mu(totalLen)/(2*pi)
