Pytheos provides a tool set for a wide range of tasks in high pressure science:

• calculate pressure from a number of built-in pressure scales
• convert pressure scales
• propagate uncertainties properly using the uncertainties package
• fit pressure-volume and pressure-volume-temperature data sets using the scipy and lmfit packages
• fit with a wide range of different equations and their combinations

Pytheos is a pure python package.

It can be installed from source or,

$ pip install pytheos

Please contact Dan Shim ([email protected]) for bug reports, comments, and suggestions. I am happy to include new pressure scales or other pressure scales in pytheos as well.

The pytheos package includes examples in Jupyter Notebook (under the examples folder), which demonstrate a range of operations, calculations, and fittings you can do with pytheos. Pytheos is designed to support data analysis using Jupyter Notebook as well as python scripts.
