Fig. 9
Left: EPIC spectra (along with the best-fit model) of Cyg OB2 #12 as observed during the third observation. Right: best-fit parameters of the EPIC spectra of Cyg OB2 #12. The top panel illustrates the observed flux (in units 10-12 erg cm-2 s-1) over the 0.5 − 10 keV energy range. The middle panel yields the column density towards the X-ray emitting plasma, whilst the bottom panel displays the two temperatures of the emission components.
