X-rays (red filled circles) plus scaled, blend-corrected Fe XII (black filled circles) of α Cen B over the span of the several joint Chandra/HST programs since SM4. Photometric uncertainty of the combined Fe XII flux is shown explicitly when larger than the symbol size (≥5%). The gray curve is the Chandra/XMM-Newton X-ray time series advanced by 16 yr (two B cycles).
