摘要:

科学产品模块(SPM)是美国对雅典娜宽视场成像仪的贡献,是一个高性能的辅助CPU,对科学数据流进行特殊处理。SPM将访问已接受的X射线事件和被机载事件识别处理拒绝的X射线事件。它将包括两个软件模块。瞬态分析模块将对科学图像进行机载处理,以识别和表征主要目标的可变性和/或检测视场中的偶然瞬态X射线源。背景分析模块将利用未遥测到地面的数据,对潜在的背景事件进行更复杂的标记,并改进背景特征,以提供改进的背景图和光谱。我们提出了SPM硬件的初步设计以及正在开发的软件算法的简要概述。

英文摘要:

The Science Products Module (SPM), a US contribution to the Athena Wide Field Imager, is a highly capable secondary CPU that performs special processing on the science data stream. The SPM will have access to both accepted X-ray events and those that were rejected by the on-board event recognition processing. It will include two software modules. The Transient Analysis Module will perform on-board processing of the science images to identify and characterize variability of the prime target and/or detection of serendipitous transient X-ray sources in the field of view. The Background Analysis Module will perform more sophisticated flagging of potential background events as well as improved background characterization, making use of data that are not telemetered to the ground, to provide improved background maps and spectra. We present the preliminary design of the SPM hardware as well as a brief overview of the software algorithms under development.
