Fast and slow light curves for the MAD0 case at i = 30°. The slow light window was chosen to correspond to the most promising time lag window for the fast light curves, as indicated by Table D.1. The color-schemes corresponding to the various frequencies for the fast (solid) and slow (dashed lines) light curves are denoted by “f” and “s”, respectively. The three windows W1, W2, and W3 are 400r_g/c in length and correspond to the LCCF panels (calculated for the slow light curves) shown at the top, analogously to Fig. 5 for fast light. The horizon-penetrating magnetic flux (Φ_B) is denoted in green (correspond to the right axis) and the horizontal (grey; only for criterion (iii) as outlined in Appendix D) bars denote the best-fitting time lag regions.
