Comparisons of fluctuations of the ID sources in position and angle before and after the modification of excitation patterns of corrector magnets in cases of solo helicity switching at ID23 and ID25 at 1 Hz. Error kicks before the modification are assumed to be 0.38 µrad (RMS) for ID23 and 0.16 µrad (RMS) for ID25. The light source fluctuations after the modification are calculated values assuming the residual error kick of 0.05 µrad at ID23 or ID25, which is our target performance of the AFC correction.
