Abstract

The HERMES Technologic and Scientific Pathfinder project is a constellation of six CubeSats aiming to observe transient high-energy events such as the Gamma Ray Bursts (GRBs). HERMES will be the first space telescope to include a siswich detector, able to perform spectroscopy in the 2 keV to 2 MeV energy band. The particular siswich architecture, which combines a solid-state Silicon Drift Detector and a scintillator crystal, requires specific calibration procedures that have not been yet standardized in a pipeline. We present in this paper the HERMES calibration pipeline, mescal, intended for raw HERMES data energy calibration and formatting. The software is designed to deal with the particularities of the siswich architecture and to minimize user interaction, including also an automated calibration line identification procedure, and an independent calibration of each detector pixel, in its two different operating modes. The mescal pipeline can set the basis for similar applications in future siswich telescopes.

HERMES 标定流水线：梅斯卡尔

HERMES 技术和科学探路者项目是一个由六颗立方体卫星组成的星座，旨在观测瞬态高能事件，如伽马射线暴（GRB）。HERMES 将是第一台包含 siswich 探测器的空间望远镜，能够在 2 keV 至 2 MeV 能段内进行光谱分析。特殊的 siswich 结构将固态硅漂移探测器和闪烁晶体结合在一起，需要特定的校准程序，而这些程序尚未在流水线中标准化。我们在本文中介绍了用于 HERMES 原始数据能量校准和格式化的 HERMES 校准管道 mescal。该软件旨在处理 siswich 结构的特殊性，最大限度地减少用户交互，还包括自动校准线识别程序，以及在两种不同的工作模式下对每个探测器像素进行独立校准。mescal 管道可为未来 siswich 望远镜的类似应用奠定基础。
