Create arbitrary boxes with isotropic power spectra
Project description
Make arbitrarily structured, arbitrary-dimension boxes and log-normal mocks.
powerbox is a pure-python code for creating density grids (or boxes) that have an arbitrary two-point distribution (i.e. power spectrum). Primary motivations for creating the code were the simple creation of log-normal mock galaxy distributions, but the methodology can be used for other applications.
Features
Works in any number of dimensions.
Really simple.
Arbitrary isotropic power-spectra.
Create Gaussian or Log-Normal fields
Create discrete samples following the field, assuming it describes an over-density.
Measure power spectra of output fields to ensure consistency.
Seamlessly uses pyFFTW if available for ~double the speed.
Installation
Simply pip install powerbox. If you want ~2x speedup for large boxes, you can also install pyfftw by doing pip install powerbox[all]. If you are a conda user, you may want to install numpy with conda first. If you want to develop powerbox, clone the repo and install with python -m pip install -e ".[dev]".
