BSD files for O4a, 50Hz to 60Hz, 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.

带采样数据（Band Sampled Data，BSD）文件旨在提供一套灵活的数据分析框架，尤其适用于连续引力波信号的搜寻工作。该探测器的观测数据取自SFDB数据库，经降采样至10 Hz后被分割为若干文件，每个文件对应10 Hz带宽的频段与1个月时长的观测数据。为去除数据中的强突发噪声脉冲，已对数据完成清洗处理。每个文件还附带包含所有相关元信息的文件头。目前已开发出多款可读取并分析该格式数据的功能函数，并已集成至SNAG库中。
