The primary objective of accelerator tuning is to correct its linear optics. This involves adjusting a large set of knobs, such as quadrupole lens gradients and alignment errors, as well as addressing various calibration errors in beam position monitors (BPMs) and other components. These errors can have a substantial impact on the performance of the accelerator. Using the full set of knobs might reduce the correction efficiency. Typically, it is advisable to prioritize the correction of large errors, as localizing them may enhance the overall efficiency of the correction process. The task of error localization is to identify and pinpoint potential sources of errors along with their location. This paper explores and compares several commonly used error localization methods using the SKIF model to test and compare their efficiency. By employing multiple methods, it becomes possible to cross-validate the results of the localization process. Combined results of several localization methods improve overall error localization.
