Evolution of the emission properties. Left: Evolution of the 0.2–8.0 keV luminosity of individual spectral components (as is labeled in the top panel). Histograms represent the fitted flux chains, converted to luminosity and corrected for absorption. Vertical lines and shaded area (following the same coding) highlight the median and 16th–84th interquintile range. There is no significant evolution either of the accretion disk (dashed) or the eruptions (dash-dotted), while the additional spectral component required for the quiescence spectrum in the first epoch becomes less significant and ultimately undetected at later epochs. Right: Same as the left panels, but showing posterior chains of the fitted temperature values. There is no significant evolution of the accretion disk temperature (solid) over the ∼3.3 yr baseline. For the eruption temperature (dash-dotted), despite the median increasing over time and the first and last epochs not being compatible at 1σ, all values are consistent within 2σ.
