bls.py 0.1.1

Prerequisites

To install and run this package, you will need to have NumPy, Cython, and AstroPy installed. The recommended installation method is:

conda install numpy cython astropy

Installation

To install, clone this repository and build the extension as follows:

git clone https://github.com/dfm/bls.py.git
cd bls.py
python setup.py install

or, install using pip:

pip install bls.py

OpenMP support: This algorithm can optionally be parallelized using OpenMP. To enable this feature, you must compile with a compiler that supports OpenMP and the relevant flags. On macOS, this can be achieved by installing a recent llvm:

brew install llvm

and then building using the following flags:

CC=/usr/local/opt/llvm/bin/clang \
 LDFLAGS="-L/usr/local/opt/llvm/lib -Wl,-rpath,/usr/local/opt/llvm/lib -liomp5" \
 CFLAGS="-I/usr/local/opt/llvm/include -fopenmp" \
 python setup.py install

On other platforms, a command like the following might be sufficient:

CFLAGS="-lgomp -fopenmp" python setup.py install

Usage

See tutorial.ipynb for a demonstration of how to use the code.
