HealSparse requires hpgeom, numpy, and astropy. If you have fitsio installed then additional features including memory-efficient concatenation of HealSparse maps are made available. Installation of healpy is required for reading full maps in HEALPix format.

HealSparse is available at pypi and conda-forge, and the most convenient way of installing the latest released version is simply:

conda install -c conda-forge healsparse


pip install healsparse

To install from source, you can run from the root directory:

pip install .
