A new part of the course on Galactic Chemical Evolution is available now. This second part follows up on the use of NuPyCEE and JINAPyCEE for two applications: constraining galaxy models, and identifying trends in chemical evolution to tune model parameters relative to observations. The video presents the interactive Jupyter notebooks, which allow to follow the course hands-on. The feedback form on the course page allows to leave comments and suggestions for the authors of the course
