MIST interpolation

Minimint (MIni Mist INTerpolation)

Software to do simple interpolation of MIST isochrones

Author: Sergey Koposov (2020) skoposov AT ed DOT ac DOT uk

Instructions

• Install minimint (clone the repo and do pip install)

git clone https://github.com/segasai/minimint.git
pip install ./minimint

• Download and prepare isochrone files

minimint.download_and_prepare()

That will download everything and process the evolutionary tracks and bolometric corrections by creating the necessary files for the package.

minimint.download_and_prepare() by by default creates bolometric corrections for these filters 'DECam', 'GALEX', 'PanSTARRS', 'SDSSugriz', 'SkyMapper','UBVRIplus', 'WISE' If you need additional filters, you can specify them using the filters parameter

minimint.download_and_prepare(filters=['JWST','WISE','DECam', 'GALEX', 'PanSTARRS', 'SDSSugriz', 'SkyMapper','UBVRIplus']) Check which filters are available on the MIST website http://waps.cfa.harvard.edu/MIST/model_grids.html This will take some time (20-30 min) and will use some space (10-30Gb).

Now you can use the package. In order to create an interpolator object:

i = minimint.Interpolator(['DECam_g','DECam_r'])

The interpolator is a callable, so you can call it on mass, log10(age), feh

ii(mass, logage,feh)

This returns a dictionary with photometry and logg, logteff, logl and photometry.
