Description

ysoisochrone is a Python package that utilizes stellar evolutionary tracks to estimate stellar masses and ages of pre-main sequence stars with a Bayesian framework.

This is the same version as v1.1.3 (and v1.1.3-exp), with a few performance updates and documentation updates. This is also used to sync with PyPI, so the new version can now be installed/updated from PyPI via pip install --upgrade ysoisochrone.
