Left: summed, flux-corrected spectra for the inner 1 25 radius surrounding Sgr A*, with the fit presented in Table 1. Spectra represent quiescent emission (ACIS-I, hollow blue circles; and HETG zeroth order, solid purple squares) and the bright flare mean emission (HETG ± first orders, solid black circles). Right: the same spectra (absent ACIS-I spectra) shown as detector counts s ⁻¹ keV ⁻¹ and now including zeroth-order spectra for the flare (hollow blue squares).
