After in interruption of beam (SPEAR loses beam or BL9 closes or running User_Restore) the M0 bend position has to be cycled to restore optimum beam collimation and energy resolution. Wait 15 minutes after full beam is restored and the beam line is open. Choose the set of commands that correspond to the particular optics configuration of the beam line.
