python-dqsegdb provides the python bindings and the client tools to
connect to LIGO/VIRGO DQSEGDB server instances.

DQSEGDB2 is a simplified Python implementation of the DQSEGDB API
as defined in LIGO-T1300625, providing a query interface for GET
requests to DQSEGDB.

The client library for the LIGO Data Replicator (LDR) service.

The DataFind service allows users to query for the location of
Gravitational-Wave Frame (GWF) files containing data from the current
gravitational-wave detectors

The gwosc package provides an interface to querying the open data
releases hosted on https://gw-openscience.org from the GEO, LIGO, and
Virgo gravitational-wave observatories.

GWpy is a collaboration-driven Python package providing tools for
studying data from ground-based gravitational-wave detectors.

GWpy provides a user-friendly, intuitive interface to the common
time-domain and frequency-domain data produced by the LIGO and Virgo
observatories and their analyses, with easy-to-follow tutorials at each
step.

Utility to find files archived by GW event trigger generators

Python library functions to simplify using International Gravitational-Wave
Observatory Network (IGWN) authorisation credentials.

This project is primarily aimed at discovering X.509 credentials and
SciTokens for use with HTTP(S) requests to IGWN-operated services.

This module provides a python LIGO Light-Weight XML I/O Library

This provides a common package for LIGO Python libraries.

The LIGO Light-Weight XML format is used extensively by compact object
detection pipeline and associated tool sets. This package provides a Python
I/O library for reading, writing, and interacting with documents in this
format.

ligo-segments defines the segment, segmentlist, and segmentlistdict objects for manipulating semi-open intervals.

This module provides a pure-python version of the `LIGOTimeGPS` class,
used to represent GPS times (number of seconds elapsed since GPS
epoch) with nanoseconds precision.

This module is primarily for use as a drop-in replacement for the
'official' `lal.LIGOTimeGPS` class (provided by the SWIG-python
bindings of [LAL](//wiki.ligo.org/DASWG/LALSuite)) for use on those
environments where LAL is not available, or building LAL is
unnecessary for the application (e.g. testing).

The code provided here is much slower than the C-implementation
provided by LAL, so if you really care about performance, don't use
this module.

Mathics is a general-purpose computer algebra system (CAS). It is meant to be a free, lightweight alternative to Mathematica.

python-Mathics-Django provides a Django front end for Mathics3, integrating GUI and help
browser.

A lexer and highlighter for Mathematica/Wolfram Language source code using the
pygments engine.

PyCBC is a software package used to explore astrophysical sources of
gravitational waves. It contains algorithms to analyze
gravitational-wave data from the LIGO and Virgo detectors, detect
coalescing compact binaries, and measure the astrophysical parameters
of detected sources.

This package provides a subclass of the Python standard library netrc.netrc
class to add some custom behaviors.

QCDLoop is a library of one-loop scalar Feynman integrals, evaluated close to
four dimensions. QCDLoop can compute one-loop integrals for tadpole, bubble,
triangle and box topologies. See arXiv:0712.1851 and arXiv:1605.03181 for
references.

Quantum ESPRESSO is an integrated suite of Open-Source computer codes for electronic-structure calculations and materials modeling at the nanoscale. It is based on density-functional theory, plane waves, and pseudopotentials.

The Rivet project (Robust Independent Validation of Experiment and Theory) is a toolkit for validation of Monte Carlo event generators. It provides a large (and ever growing) set of experimental analyses useful for MC generator development, validation, and tuning, as well as a convenient infrastructure for adding your own analyses. Rivet is the most widespread way by which analysis code from the LHC and other high-energy collider experiments is preserved for comparison to and development of future theory models.

This package provides a C++ double precision implementation of several basic geometric entities and transformations: points in 3d, directions in 3d (unit vectors), 3-vectors, points in 4d, 4-vectors, rotations, linear transformations, and boosts. The main purpose of the package is representing 4-momenta of relativistic particles and related formulae.

Root is a modular scientific software framework. It provides all the functionalities needed to deal with big data processing, statistical analysis, visualisation and storage.

Scilab is a scientific software package for numerical computations providing a powerful open computing environment for engineering and scientific applications which includes hundreds of mathematical functions with the possibility to add interactively programs from various languages (C, C++, Fortran...). It has sophisticated data structures (including lists, polynomials, rational functions, linear systems...), an interpreter and a high level programming language. Matlab and Maple files can be converted.

Sherpa is a Monte Carlo event generator for the Simulation of High-Energy Reactions of PArticles in lepton-lepton, lepton-photon, photon-photon, lepton-hadron and hadron-hadron collisions.

SPLINTER (SPLine INTERpolation) is a library for multivariate function approximation implemented in C++. The library can be used for function approximation, regression, data smoothing, and much more. Currently, the library contains the following implementations:

1. tensor product B-splines,
2. radial basis functions, including the thin plate spline, and
3. polynomial regression.

The coefficients in these models are computed using ordinary least squares (OLS). The name of the library, SPLINTER, originates from the tensor product B-spline implementation, which was the first of the methods to be implemented.
