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.本数据集归档包包含费米大视场望远镜（Fermi Large Area Telescope）的光子数据，经处理后可用于脉冲星计时研究。其包含采用泊松似然法开展脉冲星计时分析、并生成脉冲到达时间测量值的Python代码。此外还包含用于约束数据中各类噪声过程的代码与脚本，其中涵盖纳赫兹引力波背景信号。
