Tutorials

These tutorials show you how to perform a range of calculations with Galacticus. The parameter files needed for each tutorial can be found in the parameters/tutorials/ folder of the Galacticus source distribution.

The later tutorials build on ideas presented in the earlier ones, so it is recommended to work through them in order.
