MIST Isochrone Grids

ArtPop can work with synthetic photometry generated from any source, provided it is in the correct format. For convenience, we provide built-in tools for fetching and manipulating synthetic photometry from the MIST isochrone models. See, for example, the MISTSSP and MISTSersicSSP classes.

The first time you need a particular MIST synthetic photometry grid, it will be downloaded and saved to your MIST_PATH. If this environment variable is not set, the grid(s) will be saved in ~/.artpop/mist.

To change the default path location, create an environment variable called MIST_PATH.

For example, in bash, add this to your .bashrc file:

export MIST_PATH='/path/to/your/MIST/grids'

ArtPop will use this path by default in all functions that use the MIST grids. Note, however, that you always have the option to pass a different path to any function that uses a MIST grid.
