Left panel: observed Chandra 50 ks spectrum and residuals of HS 1700+6416, modeled with a power law modified by Galactic absorption plus intrinsic neutral absorption. The counts are binned to a minimum significant detection of 3σ (and a maximum of 15 counts per bin) only for plotting purposes. Right panel: observed Chandra spectrum and residuals of the source obtained from the eight observations of 2007. The same model and binning strategy as in the left panel are used. The Chandra background is shown in red.
