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 is made available along with the XSM Data Analysis Software from ISRO Science Data Archive (ISDA) hosted 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.

印度Chandrayaan-2号登月任务的太阳X射线监测仪（XSM）仪器以软X射线对太阳进行宽带光谱分析。XSM具有其独特的功能，例如低背景，高时间节奏和高光谱分辨率，即使在活动较少的时期，也提供了表征来自太阳的瞬态和静态X射线发射的机会。它以一秒的节奏记录X射线光谱，并定期下载船上记录的数据以及其他有效载荷的数据。在地面预处理期间，将隔离XSM数据，并且在有效负载运营中心（POC）可以将0级数据用于更高级别的处理。XSM数据分析软件（XSMDAS）的开发目的是将0级数据处理到更高水平，并为用户定义的装仓参数生成校准后的光曲线和光谱，使其适合于进一步的科学分析。还开发了名为XSM快速查看显示（XSMQLD）的XSMDAS的前端，以方便在不进行校准的情况下首次查看数据。XSM数据管理监控系统（XSMDMS）旨在在POC上执行自动数据处理，并维护SQLite数据库以及有关数据集的相关信息以及用于监视数据质量和仪器运行状况的内部Web应用程序。所有XSM原始数据和已校准的数据产品均采用FITS格式，并组织为每日文件，并且数据存档遵循Planetary Data System-4（PDS4）标准。XSM数据与印度空间科学数据中心（ISSDC）托管的ISRO科学数据档案（ISDA）的XSM数据分析软件一起提供。在这里，我们讨论用于XSM数据处理的软件所有组件的设计和实现以及XSM数据归档的内容。
