“…The soft X-ray spectrum of Mkn 3 is extremely complex, but the spectral resolution of the XIS is significantly worse (at all energies) than the gratings aboard Chandra and XMM-Newton (∼ 1−2 orders of magnitude worse than the medium-energy Chandra grating, depending on the energy). Previous studies of Mkn 3 using Chandra and XMM-Newton gratings have shown numerous atomic features, indicative of a predominantly photoionized spectrum originating in material with a wide range in ionization states (Sako et al 2000;Pounds et al 2005;Bianchi et al 2005;Awaki et al 2008). Thus, when grating spectra are available, CCD data cannot contribute substantially new understanding of the origin of the soft X-ray spectrum since many emission and absorption features are blended together.…”

“…1 that above ∼ 2 keV the spectrum is very flat due to absorption and reflection, and there is complex structure around the Fe Kα emission line in the ∼ 6−8 keV Fe K band. The spectrum steepens towards low energies and below ∼ 3 keV there are many emission and absorption features, which have been well-studied with both CCD and higher spectral resolution instrumentation (Sako et al 2000;Pounds et al 2005;Bianchi et al 2005;Awaki et al 2008).…”

“…2 The others are hard X-ray telescopes (HXTs) covering up to ∼ 80 keV. 3 One SXT is for soft X-ray spectroscopy (SXS : X-ray micro-calorimeter detector) with a high resolution spectroscopy. The FOV is 3.05 arcmin with the pixels of 6 × 6.…”

“…ASTRO-H will mount three kinds of X-ray detectors: an X-ray micro-calorimeter (SXS 2 ), a Soft X-ray Imager (SXI 3,4 ) a hard X-ray imager (HXI 5 ), and a soft Gamma-ray Detector (SGD 6 ). The SXS, SXI and HXI are mounted on ASTRO-H as the focal plane detectors of two Soft X-ray telescope (SXT1 and SXT2 7 respectively) and the Hard X-ray telescope (HXI) 8 , respectively. Our team has developed the X-ray CCD's (SXI; Soft X-ray Imager) onboard ASTRO-H (Tsunemi et al 2013; Hayashida et al 2014).…”
