我们已经开发了一个框架的蒙特-卡罗模拟的X射线望远镜（XRT）和X射线成像光谱仪（XIS）的朱雀，主要是空间和光谱复杂的天体源的科学分析。在ANL平台上建立了一个光子-光子仪器模拟器，该模拟器已成功应用于ASCA数据分析。该模拟器具有模块化结构，其中XRT模拟基于光线跟踪库，而XIS模拟利用由其他工具单独生成的光谱“重分布矩阵文件”（RMF）。仪器特性和校准结果，例如，XRT几何形状、反射率、相互对准、热屏蔽传输、XIS光学阻挡滤光片（OBF）上的污染物积聚都尽可能完整地纳入其中。这些信息大多以FITS（灵活图像传输系统）文件的形式在标准校准数据库（CALDB）中提供。该模拟器还可用于生成“辅助响应文件”（ARF），其描述XRT响应和OBF污染量。ARF取决于天体目标的空间分布和探测器上的光子积累区域，以及观测条件，如观测日期和卫星姿态。我们描述的模拟器和ARF发生器的原理，并证明其性能与飞行中的数据比较。
We have developed a framework for the Monte-Carlo simulation of the X-Ray Telescopes (XRT) and the X-ray Imaging Spectrometers (XIS) onboard Suzaku, mainly for the scientific analysis of spatially and spectroscopically complex celestial sources. A photon-by-photon instrumental simulator is built on the ANL platform, which has been successfully used in ASCA data analysis. The simulator has a modular structure, in which the XRT simulation is based on a ray-tracing library, while the XIS simulation utilizes a spectral "Redistribution Matrix File" (RMF), generated separately by other tools. Instrumental characteristics and calibration results, e.g., XRT geometry, reflectivity, mutual alignments, thermal shield transmission, build-up of the contamination on the XIS optical blocking filters (OBF), are incorporated as completely as possible. Most of this information is available in the form of the FITS (Flexible Image Transport System) files in the standard calibration database (CALDB). This simulator can also be utilized to generate an "Ancillary Response File" (ARF), which describes the XRT response and the amount of OBF contamination. The ARF is dependent on the spatial distribution of the celestial target and the photon accumulation region on the detector, as well as observing conditions such as the observation date and satellite attitude. We describe principles of the simulator and the ARF generator, and demonstrate their performance in comparison with in-flight data.
