MALIGN

A misalignment of the beam, implemented as a zero-order matrix.
Parallel capable? : yes

The default value of the PASS parameter (-1) means that the misalignment is imposed on the beam every pass. This is appropriate for static misalignments. When using the MALIGN element to kick the beam for beam dynamics studies in rings, PASS>=0 is required. If PASS=0, closed orbit computation and correction will include the effect of the kick; however, matrix-based computations by default will not (set FORCE_MODIFY_MATRIX=1 to change this). If PASS>0, then closed orbit computation and correction do not include the kick, which is probably what is desired in beam dynamics studies in rings.
