mapsims Documentation

mapsims is a Python 3 package to produce map based simulations for the Simons Observatory.

It creates simulated Simons Observatory maps based on:

  • Foreground models included in PySM

  • Custom foregrounds models from the so_pysm_models package, currently so_pysm_models.GaussianDust and so_pysm_models.GaussianSynchrotron

  • Precomputed Cosmic Microwave Background simulations

  • Noise simulations based on expected performance and simulated hitmaps with either classical or opportunistic scanning strategy

  • Effect of gaussian beam convolution
