Nemo - a Sunyaev-Zel’dovich effect galaxy cluster and source finder
Nemo is a millimeter-wave Sunyaev-Zel’dovich galaxy cluster and compact source detection package, originally developed for the Atacama Cosmology Telescope project, and capable of analyzing maps that will be produced by the Simons Observatory.

Installation:
pip install nemo-szSupport: Please use the GitHub issues page, and/or contact Matt Hilton.
Nemo is written in Python and provides several modules that may be useful for analyzing ACT/SO data, in addition to the command-line programs provided in the package.
Nemo is not the pipeline used for Hasselfield et al. (2013), but implements many of the ideas presented there. It is the package that was used to produce the ACT DR3 cluster catalog, and the ACT DR5 cluster catalog. All ACT data products are available from LAMBDA.
Nemo is under active development, and not all documentation or example config files are up to date (some may contain references to files that are not yet publicly available). The package also contains some experimental features that are not necessarily well tested.
If you need to acknowledge the use of Nemo, please cite Hilton et al. (2021).
