One of the methods, linear optics from closed orbits (LOCO), is widely employed to correct linear optics. Due to the ring nature, a quadrupole error at a location of the ring affects the entire orbit response measurement data. The orbit response, however, can be localised to a certain range of the ring when an orbit feedback (or correction) is applied to the rest of the ring. The quadrupole errors located in the range, where the feedback is acting, then have no impact, and the ring optics can be locally examined. An application of this technique to Swiss light source is discussed.
