About The Project

The LiteBIRD Simulation Framework is being developed for the LiteBIRD collaboration.

Built With

• Love!
• Python 3
• Poetry
• NumPy
• Astropy
• Healpix
• Sphinx
• Numba
• ducc

Getting Started

Refer to the documentation to learn how to install the LiteBIRD simulation framework on your computer or on a HPC cluster.

Usage

An example notebook is avalable here.

The documentation is available online at litebird-sim.readthedocs.io/en/master/.

To create a local copy of the documentation, make sure you ran poetry with the flag --extras=docs, then run the following command:

• Linux or Mac OS X:

  ./refresh_docs.sh
  

• Windows:

  poetry shell
  cd docs
  make.bat html
  

Focal plane visualizer

We can visualize detectors in the focal plane by:

python -m litebird_sim.plot_fp

This software loads the IMo which is installed in the machine you are using. As the conversation unfolds, an interactive Matplotlib window will appear. Detectors corresponding to the specified channels are represented as blue dots. Clicking on a dot reveals the DetectorInfo for that detector in real time, highlighted with a red star. Additionally, if you agree during the conversation to generate a detector file, a list of starred detectors will be saved into a text file at the designated location after you closed the plot.

Roadmap

See the open issues for a list of proposed features (and known issues).
