A Python package by Nihan Pol, MAPS aims to simplify the task of searching for anisotropies in the nanohertz gravitational wave sky observed with PTAs.
As of now, the easiest way to install MAPS is to use pip+git:
pip install git+https://github.com/NihanPol/MAPS@main
This has had the fewest problems and is likely the easiest way to get MAPS working.
While there are a few examples for using MAPS found in the maps/docs folder, anis_pta.py has been overhauled to be more explicit in its documentation. If you are using VSCode or Jupyter notebooks, the doc comments should appear when attempting to use a command. If things are not clear, that likely isn't your fault, and raising a github issue with the problem will bring our attention to it and fix it!
