TL;DR: In this article, a framework for the Monte-Carlo simulation of X-Ray Telescopes (XRT) and X-ray Imaging Spectrometers (XIS) onboard Suzaku was developed for the scientific analysis of spatially and spectroscopically complex celestial sources.
Journal ArticleDOI
Reproducibility of Non-X-ray Background for the X-ray Imaging Spectrometer aboard Suzaku
Noriaki Tawa,Kiyoshi Hayashida,Masaaki Nagai,Hajime Nakamoto,Hiroshi Tsunemi,Hiroya Yamaguchi,Yoshitaka Ishisaki,Eric D. Miller,Tsunefumi Mizuno,Tadayasu Dotani,Masanobu Ozaki,Haruyoshi Katayama +11 more
TL;DR: In this article, the authors constructed an X-ray non-X-ray background (NXB) database by collecting XIS events when the dark Earth covers the XIS FOV and found that the count rate of the NXB anti-correlates with the cut-off-rigidity and correlates with the PIN upper discriminator (PIN-UD).
