PSR B1937+21 Giant Pulse Baseband Data Release

This is a companion dataset to go with the publication, <strong>"Using Giant Pulses to Measure the Impulse Response of the Interstellar Medium"</strong> by <em>Mahajan and van Kerkwijk, (2023). </em>https://arxiv.org/abs/2305.13274 The data files contain the baseband snippets PSR B1937+21 giant pulses found using the giant pulse search technique described in the paper. <strong>Requirements</strong><br> To load and work with the data files, you will need the Python package: pulsarbat v0.0.9<br> We have provided an <em>environment.yml</em> that can be used to conveniently create a conda environment to work with the data. <strong>Usage</strong><br> An example script is provided (<em>script.py</em>) which shows how to load the data in Python. <strong>Data Format</strong><br> The data files are zipped in <em>B1937GPs.zip</em>. The giant pulse data was serialized using Python's <em>pickle</em> library. Each file contains<br> a list of <em>pulsarbat.DualPolarizationSignal</em> objects from the <em>pulsarbat </em>package. There are 38 data files with names: <em>B1937GPs/B1937GPs_{MJD}_{freq}.pb</em> <em>MJD </em>refers to the date of the observation <em>freq </em>refers to the center frequency of the band in MHz. There were two observations at MJD 58245 and MJD 58298, and data from 19 contiguous frequency bands is provided (thus, a total of 38 files). The md5 checksums for all files is provided in <em>md5_checksums.txt</em>.本数据集为配合论文《利用巨脉冲测量星际介质的冲激响应（Using Giant Pulses to Measure the Impulse Response of the Interstellar Medium）》（Mahajan与van Kerkwijk，2023）[arXiv:2305.13274] 制作的配套数据集。 数据文件包含通过论文所述巨脉冲搜索技术识别出的PSR B1937+21巨脉冲基带片段。 **使用要求**：若要加载并处理该数据文件，需安装Python第三方库pulsarbat v0.0.9。我们已提供environment.yml文件，可通过该文件便捷创建适配本数据集的conda环境。 **使用方法**：我们提供了示例脚本script.py，演示如何在Python环境中加载本数据集。 **数据格式**：所有数据文件打包存储于B1937GPs.zip压缩包中。巨脉冲数据采用Python的pickle库进行序列化存储。每个文件均包含一个列表，其中存储的是pulsarbat库的双极化信号（DualPolarizationSignal）对象。本数据集共包含38个数据文件，文件名格式为`B1937GPs/B1937GPs_{MJD}_{freq}.pb`，其中MJD代表观测日期对应的修正儒略日，freq代表观测频段的中心频率，单位为MHz。本次观测共有两次，分别对应修正儒略日58245与58298，且提供了19个连续频段的观测数据，因此总计生成38个数据文件。所有文件的md5校验和均已在md5_checksums.txt文件中给出。
