From top to bottom: evolution of the photon index (measured using the M_pl model), ratio of the f_{0.2 − 2.0 keV} to the 2246 Å monochromatic flux, apparent UVM2 AB magnitude, and log(f_{0.2 − 2.0 keV}) against the time offset. The time off-set is calculated relative to the inferred t₀ assuming a period of 223 days. The whole data set was split into three cycles that were determined by the time when the rapid X-ray flux drop occurred. The vertical dashed lines represent the time (relative to t₀ of each cycle) of the ATCA radio observations. Radio emission was detected only in cycle 3 (dashed blue lines).
