oa :Average lead deviation over useful path Lu.A straight line representing the tendency of the cumulative actual lead. This is obtained by the least square method and measured by the laser system. The value is added by path compensation over the useful path and the mean travel deviation.C:Path compensation over useful path Lu.Selection parameter:This value is determined by customer and maker as it depends on different application requirements.e
