X-ray light curve (0.3–8 keV) of AX J0049.4−7323 obtained from Swift/XRT, Chandra, XMM-Newton, and RXTE data analysed in this work, and ASCA data from Yokogawa et al. (2000). INTEGRAL points are in the energy range 20–40 keV. Downward arrows are used to indicate 3σ upper limits. Grey vertical lines show the times of periastron passages according to the ephemeris calculated by Schmidtke et al. (2013). The right y-axis shows the absorbed 0.3–8 keV X-ray luminosity, assuming d = 62 kpc. Error bars indicate the 1σ uncertainties.
