MCMole3D (Monte-Carlo MOlecular Line Emission) simulates the 3D molecular cloud emission in the Milky Way. In particular, it can simulate both the unpolarized and polarized emission coming from the first rotational line of Carbon Monoxide (CO, J=1-0). MCMole3D seeks to compare the simulated emission with that observed by full sky surveys from the Planck satellite.

s4cmb (Systematics For Cosmic Microwave Background) studies the impact of instrumental systematic effects on measurements of CMB experiments based on bolometric detector technology. s4cmb provides a unified framework to simulate raw data streams in the time domain (TODs) acquired by CMB experiments scanning the sky, and to inject in these realistic instrumental systematics effect.
