Software and data release for Fermi Pulsar Timing Array

The archive include photon data from the Fermi Large Area Telescope, processed to enable its use for pulsar timing.  It includes Python code for performing pulsar timing using Poisson likelihood and for producing pulse time-of-arrival measurements.  It further includes code and scripts for constraining noise processes in the data, including the a signal from the nanohertz gravitational wave background.

See README for more information.

本数据集档案包含来自费米大面积望远镜（Fermi Large Area Telescope）的光子数据，经预处理后可用于脉冲星计时（pulsar timing）任务。数据集附带可基于泊松似然（Poisson likelihood）实现脉冲星计时、生成脉冲到达时间（pulse time-of-arrival）测量结果的Python代码。此外还包含用于约束数据中各类噪声过程（包括纳赫兹引力波背景（nanohertz gravitational wave background）信号）的代码与脚本。

详见README文件以获取更多信息。
