Notes: ^a Telescope and instrument used for observation. ACIS-S count rates are from Galache et al. (2007).
^b Dead time corrected exposure time of the observation.
^c Start date of the observation.
^d Time in days after the last X-ray non-detection of SS2 on 2007 July 22.55 (JD = 2454304).
^e Source count rates, X-ray luminosities (unabsorbed, blackbody fit, 0.2-1.0 keV) and upper limits were estimated
according to Sect. 2.2.
