Upper panel: XRT 0.3 to 1 keV background-corrected fluxes (diamonds) or upper limits (downward arrows) where appropriate, plotted against a time-axis given in the day of year. We also plot the predicted X-ray flux (red crosses, normalised to the tenth observation) as described in the text. Middle panel: solar wind proton flux as measured by STEREO A for early 2009. Lower panel: N_gas (open diamonds), or upper limits (downward arrows) where appropriate.
