Soft X-ray (0.2–2 keV) light curves for all the sources in our sample. Count rates of the different telescopes were converted to the 0.2–2.0 keV range using PIMMS under the assumption that the spectral shape can be described by a power law with a photon index of 1.7 and absorption in our Galaxy alone. Circles represent detections, while triangles symbolise 95% upper limits on the flux. All error bars are 1σ.
