Minimint (MIni Mist INTerpolation)
Software to do simple interpolation of MIST isochrones.
Author: Sergey Koposov (2020-2021) skoposov __AT__ ed __DOT__ ac __DOT__ uk
# Instructions
* Install minimint. You can either pip install the released version or install from github
```
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 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 (10-30 Gb).
If you want to put those processed isochrone files in a location different from the site-packages folder of minimint, you can use the outp_prefix parameter of `download_and_prepare`. You then will need to either specify the location each time when you construct the interpolators or with the MINIMINT_DATA_PATH environment variable
# Usage
In order to create an interpolator object for two filters (your can provide a list of any numbers of filters)
```ii = 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, logg, logteff and logl.
You also can use the interpolator to find the maximum valid mass on the isochrone.
```ii.getMaxMass(logage, feh)```
# Examples
See the [notebook](examples/Example.ipynb) in the examples folder
## Synthetic stellar populations
If you are interested in synthetic stellar populations you will need
the implementation of the IMF. For this you may want to use https://github.com/keflavich/imf
