LIGO Scientific Collaboration Algorithm Library - minimal Python package

LALSuite is the LIGO Scientific Collaboration Algorithm Library for gravitational-wave analysis. Its primary purpose is searching for and characterizing astrophysical signals in gravitational-wave time series data, particularly data from ground-based detectors such as LIGO and Virgo.

LALSuite consists of a set of configure-make-install style software packages organized by problem domain or source classification. This Python package provides a standalone, dependency-free binary distribution of the libraries and Python modules in LALSuite for Linux and macOS.

Installing LALSuite from the Python Package Index requires pip >= 19.3.

To install, simply run:

$ pip install lalsuite

Optional dependencies, which can be installed as pip install lalsuite[option]:

• lalinference (pulls in gwdatafind and gwpy)

• lalpulsar (pulls in solar_system_ephemerides to provide ephemeris files which, until LALSuite 7.15, were still included in the main package)

• test (pulls in pytest)
