Downloading Grids

Synthesizer relies on pre-computed grids of spectra from stellar population synthesis models. Full details are provided in the Grids section of the documentation; here we describe how to download a simple test grid, which will enable you to run the examples and start to explore synthesizer.

Downloading the test grid

Synthesizer contains a simple command line helper tool for downloading the test grid. This test grid should not be used for production runs (please see here for details) but is sufficient for running the examples and understanding the code. It is based on the BC03 stellar population synthesis model, and contains the stellar emission in the UV–optical on an age–metallicity grid.

To download the test grid, cd into the root synthesizer directory and run the synthesizer-download helper as follows:

cd synthesizer
synthesizer-download --test-grids -d tests/test_grid/ --dust-grid
