Chandrayaan-2太阳X射线监测仪数据处理软件
Data Processing Software for Chandrayaan-2 Solar X-ray Monitor
摘要：
印度月船2号月球飞行任务的太阳X射线监测仪（XSM）在软X射线中对太阳进行宽带光谱分析。XSM具有低背景、高时间节奏和高光谱分辨率等独特功能，即使在低活动期间，也可以表征太阳的瞬态和静态X射线发射。它以一秒的节奏记录X射线光谱，机载记录的数据与其他有效载荷的数据一起定期下载。在地面预处理期间，XSM数据被隔离，并且0级数据可用于有效载荷操作中心（POC）的更高级别的处理。XSM数据分析软件（XSMDAS）的开发是为了将0级数据处理到更高的水平，并为用户定义的分箱参数生成校准的光变曲线和光谱，以便其适合于进一步的科学分析。还开发了一个名为XSM快速查看显示器（XSMQLD）的XSMDAS前端，以便于在不应用校准的情况下首次查看数据。XSM数据管理-监测系统（XSMDMS）旨在在POC进行自动化数据处理，并维护SQLite数据库（包含数据集的相关信息）和内部Web应用程序（用于监测数据质量和仪器运行状况）。所有XSM原始和校准数据产品均采用FITS格式，组织为按天文件，数据档案遵循行星数据系统-4（PDS 4）标准。XSM数据将在锁定期后与印度空间科学数据中心（ISSDC）的ISRO科学数据档案馆（ISDA）的XSM数据分析软件一起提供。在这里，我们讨论的设计和实现的XSM数据处理和XSM数据归档的内容的软件的所有组件。
英文摘要：
Solar X-ray Monitor (XSM) instrument of India's Chandrayaan-2 lunar mission carries out broadband spectroscopy of the Sun in soft X-rays. XSM, with its unique features such as low background, high time cadence, and high spectral resolution, provides the opportunity to characterize transient and quiescent X-ray emission from the Sun even during low activity periods. It records the X-ray spectrum at one-second cadence, and the data recorded on-board are downloaded at regular intervals along with that of other payloads. During ground pre-processing, the XSM data is segregated, and the level-0 data is made available for higher levels of processing at the Payload Operations Center (POC). XSM Data Analysis Software (XSMDAS) is developed to carry out the processing of the level-0 data to higher levels and to generate calibrated light curves and spectra for user-defined binning parameters such that it is suitable for further scientific analysis. A front-end for the XSMDAS named XSM Quick Look Display (XSMQLD) is also developed to facilitate a first look at the data without applying calibration. XSM Data Management-Monitoring System (XSMDMS) is designed to carry out automated data processing at the POC and to maintain an SQLite database with relevant information on the data sets and an internal web application for monitoring data quality and instrument health. All XSM raw and calibrated data products are in FITS format, organized into day-wise files, and the data archive follows Planetary Data System-4 (PDS4) standards. The XSM data will be made available after a lock-in period along with the XSM Data Analysis Software from ISRO Science Data Archive (ISDA) at Indian Space Science Data Center(ISSDC). Here we discuss the design and implementation of all components of the software for the XSM data processing and the contents of the XSM data archive.
