Introduction

moby2 is a Python package (with compiled C extensions) to support the analysis of time-ordered data and single-observation maps for the Atacama Cosmology Telescope (ACT) Polarimeter (ACTPol). It is derived from an earlier package, moby, which filled the same purpose during the MBAC era of ACT (2007-2010).

The public ACT website is https://act.princeton.edu/. The home of the ACT Collaboration on github is https://github.com/ACTCollaboration/.

The code here has been developed over the course of many years, and some features or modules have been actively maintained while others have not. The documentation is in many cases misleading, inaccurate, or irrelevant.

This code and documentation was made public in March 2020, as part of supporting the development of the Simons Observatory (SO) pipeline. ACTPol continues to observe, and moby2 will continue to play a role in low-level data analysis. Future improvements to this documentation will likely only be made insofar as they are useful to SO development or on-going ACTPol operations.

Most of moby2 is compatible with both Python 2 and Python 3, and must remain so until all dependent sites have fully upgraded.
