How to GLEE

This section contains everything you need to run GLEE, from understanding the configuration file to working through hands-on tutorials.

What's in this section?​

  • The GLEE Configfile — The primary reference for the plain-text control file that drives every GLEE run. Covers global settings, lens and source definitions, parameter flags, priors, and linking.
  • glee.py Wrapper — A Python wrapper that exposes additional optimisers (SciPy, emcee), chi-squared computation, and more.
  • Tutorials — Step-by-step guides from preparing your data to fitting a full surface brightness model.
