PINT: Maximum-Likelihood Estimation of Pulsar Timing Noise Parameters

PINT is a project to develop a pulsar timing solution based on python and modern libraries. It is still in active development, but it is in production use by the NANOGrav collaboration and it has been demonstrated produce residuals from most "normal" timing models that agree with Tempo and Tempo2 to within ~10 nanoseconds. It can be used within python scripts or notebooks, and there are several command line tools that come with it.

The primary reasons PINT was developed are:

To have a robust system to produce high-precision timing results that is completely independent of TEMPO and Tempo2
To make a system that is easy to extend and modify due to a good design and the use of a modern programming language, techniques, and libraries.
