PINT: A Modern Software Package for Pulsar Timing

Abstract Over the past few decades, measurement precision of some pulsar timing experiments has advanced from ∼10 μ s to ns, revealing many subtle phenomena. Such high demands both careful data handling and sophisticated models avoid systematic error. To achieve these goals, we present PINT ( P INT I N ot T empo3 ), a high-precision Python analysis package, which is hosted on GitHub available Package Index (PyPI) as pint-pulsar . well tested, validated, object oriented, modular, enabling interactive providing an extensible flexible development platform for applications. It utilizes well-debugged public packages (e.g., um y A stropy libraries) modern software schemes version control efficient with git GitHub) continually expanding test suite improved reliability, accuracy, reproducibility. developed implemented without referring to, copying, or transcribing code other traditional Tempo / Tempo2 ) therefore provides robust tool cross-checking analyses simulating pulse arrival times. In this paper, describe design, use, validation , compare results between it
