BSD files for O4a, 100Hz to 110Hz, Livingston

Band Sampled Data (BSD) files are meant to provide a flexible data analysis framework, particularly suitable for the search of continuous gravitational wave signals.The detector’s data are taken from the SFDB data base, downsampled to 10 Hz and divided into files containing 10 Hz wide bands and 1 month of data. Cleaning is applied, in order to remove strong glitches from the data. Each file also contain headers with all the relevant information. Several functions to read and analyse the data in this format have been developed and are attached to the SNAG library.

带通采样数据（Band Sampled Data，BSD）文件旨在构建灵活的数据分析框架，尤其适用于连续引力波信号的搜寻任务。探测器相关数据取自SFDB数据库，经降采样至10赫兹，并被分割为多个文件，每个文件涵盖10赫兹带宽的频段，且对应1个月时长的观测数据。为去除数据中的强数据毛刺（glitch），已对数据执行清洗处理。每个文件均附带包含所有相关信息的文件头。目前已开发出多款可读取并分析该格式数据的函数，并已集成至SNAG库中。
