CosmoSim

The purpose of CosmoSim is to simulate gravitation lenses. In other words, giving a model of a lens and a model of a source, it can generate the distorted image of the source as seen through the lens.

Architecture

The CosmoSim software suite consists of three layers.

1. The simulator library, simlib
2. The python wrapper, CosmoSimPy
3. A range of executable python scripts, including the GUI CosmoGUI.py and the batch generator datagen.py.

The mathematical model is implemented in the simulator library, which is consequently the most important part to document properly.

(Architecture updated in version 2.5.1. See also v2.5.0.)

Python modules

All python code is collected in the CosmoSimPy directory

• CosmoSim
  • Python package wrapping the simulator library.
• Arguments.py
  • Argument parser and other shared functions for the scripts.
