Grids¶
Introduction¶
Most of the functionality of Synthesizer is reliant on grid files. These are typically precomputed multi-dimensional arrays of spectra (and lines) from Stellar Population Synthesis (SPS) models for a range of ages and metallicities, and potentially other parameters (see below). Grids can also represent the emission from other sources, e.g. active galactic nuclei.
There is a low-resolution test grid available via the synthesizer-download command line tool, but for actual projects you will need to download one or more full production grids from Box. See details below on where on your system to download these grids and how to load them.
