Model fit to data from the Chambon-la-Forêt observatory (CLF, latitude \(48.024^{\circ }\) N, longitude \(2.259^{\circ }\) E). Disturbed times (according to the data selection criteria used in the modeling) are shown with a gray background. Observatory data (corrected for the fields of other sources, as indicated in the main text) are shown as black crosses. Model predictions are shown as red dots. Days (abscissa axis) are counted in Modified Julian Days 2000 (MJD2000, referenced to January 1, 2000, at 00 UT)
