simim 0.3.11

Code for simulating the radio, sub-mm and FIR sky

SimIM

SimIM is a tool for simulating the extra-galactic sky in radio, sub-mm and far-infrared. Full documentation is available via Read the Docs. Source code is avialable via GitHub.

This is Version 0.3, which includes utilities for downloading and formatting simulation data, adding new properties such as spectral line emission to simulations, visualizing basic data products, constructing light cones, making pixelized maps or data cubes, and mocking instruments/timestreams. A future release will add more detailed documentation with examples of all functionality and relevant scientific applications.

What's Here

1. simim directory - source code for the SimIM package
2. setupsimim.py - script for completing SimIM setup when building from GitHub source code
3. docs directory - code for building documentation
4. tests directory - unit tests; these cover more recent additions to the SimIM source code but are relatively sparse for the galprops, lightcone, and siminterface modules.
5. pyproject.toml, .readthedocs.yaml, .gitignore - config files for pip, readthedocs, and git
