Database II of Single pulses from the Parkes telescope

This is an updated Parkes transient database (PTD II) for https://data.csiro.au/collection/csiro:42640. PTD II contains 165,592 single pulses from 363 known pulsars. Unlike previous databases while maintaining a compact size of only 1.5 GB. The database employs a sqlite3 structure organising pulsar metadata, observation files, and pulse events with their raw data stored in binary format. We provide processing tools (get_pulsar_pub.py) for extracting and analysing single-pulse data, enabling fluence fitting and statistical analysis.

本数据集为更新版帕克斯瞬变源数据库（Parkes Transient Database II，简称PTD II），相关数据可通过https://data.csiro.au/collection/csiro:42640获取。PTD II共收录来自363颗已知脉冲星的165592个单脉冲信号。相较于此前的同类数据库，本数据库仅占用1.5 GB的存储空间，体积小巧紧凑。本数据库采用sqlite3结构进行组织，涵盖脉冲星元数据、观测文件以及脉冲事件相关信息，其原始数据以二进制格式存储。我们配套提供了用于单脉冲数据提取与分析的处理工具（get_pulsar_pub.py），可实现能流拟合与统计分析功能。
