Involved Projects and Packages
ParaView is an application designed with the need to visualize large data
sets in mind.
ParaView runs on distributed and shared memory parallel as well as single
processor systems and has been successfully tested on Windows, Linux and
various Unix workstations and clusters. Under the hood, ParaView uses the
Visualization Toolkit as the data processing and rendering engine and has a
user interface written using a unique blend of Tcl/Tk and C++.
This package contains some example data for Paraview.
PLplot is a library of functions that are useful for making scientific
plots.
PLplot can be used from within compiled languages such as C, C++,
FORTRAN and Java, and interactively from interpreted languages such as
Octave, Python, Perl and Tcl.
The PLplot library can be used to create standard x-y plots, semilog
plots, log-log plots, contour plots, 3D surface plots, mesh plots, bar
charts and pie charts. Multiple graphs (of the same or different sizes)
may be placed on a single page with multiple lines in each graph.
A variety of output file devices such as Postscript, png, jpeg, LaTeX
and others, as well as interactive devices such as xwin, tk, xterm and
Tektronics devices are supported. New devices can be easily added by
writing a small number of device dependent routines.
There are almost 2000 characters in the extended character set. This
includes four different fonts, the Greek alphabet and a host of
mathematical, musical, and other symbols. Some devices supports its own
way of dealing with text, such as the Postscript and LaTeX drivers, or
the png and jpeg drivers that uses the Freetype library.
This package provides the shared libraries for PLplot.
Praat is an open-software tool for the analysis of speech in phonetics.
Through its graphical interface, several speech analysis functionalities
are available: spectrograms, cochleograms, and pitch and formant extraction.
Articulatory synthesis, as well as synthesis from pitch, formant, and
intensity are also available. Other features are segmentation, labelling
using the phonetic alphabet, and computation of statistics.
Praat is configurable and extensible through its own scripting language and has
provisions for communicating with other programs.
Pythia can be used to generate high-energy-physics ‘events’, i.e. sets of outgoing particles produced in the interactions between two incoming particles. The objective is to provide as accurate as possible a representation of event properties in a wide range of reactions, within and beyond the Standard Model, with emphasis on those where strong interactions play a role, directly or indirectly, and therefore multihadronic final states are produced. The physics is then not understood well enough to give an exact description; instead the program has to be based on a combination of analytical results and various QCD-based models. Extensive information is provided on all program elements: subroutines and functions, switches and parameters, and particle and process data. This should allow the user to tailor the generation task to the topics of interest.
A python wrapper around CASACORE, the radio astronomy library
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 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.
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.
