This algorithm identifies spherical underdensities in a cosmological volume. It works on periodic cosmological simulations, as well as on observational galaxy surveys. Examples of its application in astronomy research can be found in https://arxiv.org/abs/1810.02864 or https://arxiv.org/abs/1609.00101.
Under the main directory, compile the package with python setup.py build, and then install it with python setup.py install.
Requirements:
Python>= 3.0.0GCC>= 4.2.1Scipy>= 1.5.0
Earlier versions of those software packages might work as well, but they have not been tested.
Examples of the usage of the package can be found under the examples/ directory.
