Debian Science Physics packages

CERNLIB is a suite of data analysis tools and libraries created for use in physics experiments, but also with applications to other fields such as the biological sciences.

This metapackage provides almost all of the programs and libraries contained in CERNLIB. Most people will likely want only a subset of these. A few extra CERNLIB programs, not of interest to many people, may be obtained via the cernlib-extras metapackage.

FDMNES calculates the spectra of different spectroscopies related to the real or virtual absorption of x-ray in material. It gives the absorption cross sections of photons around the ionization edge, that is in the energy range of XANES in the EXAFS. The calculation is performed with all conditions of rectilinear or circular polarization. In the same way, it calculates the structure factors and intensities of anomalous or resonant diffraction spectra (DAFS or RXD). FDMNES also allows the comparison of the simulated spectra to experimental ones with the help of objective criteria.

GEANT is a framework for simulating the passage of subatomic particles through matter, for instance, particle detectors. For maximum flexibility, GEANT simulations are performed by linking FORTRAN code supplied by the user with the GEANT library, then running the resulting executable.

This package includes gxint, a script that makes this linking step more convenient.

Geant4 is a toolkit for the simulation of the passage of particles through matter. Its areas of application include high energy, nuclear and accelerator physics, as well as studies in medical and space science.

This is a metapackage depending on all libraries.

A collection of programs for images that are generated during a Particle Image Velocimetry (PIV) experiment. This is a technique to obtain the velocity field of a fluid flow quantitatively and is performed by tracking tracer particles that have been seeded to a fluid. The technique is also applied for observing deformations at surfaces of (solid) bodies. The package contains:

an image processing program for typical filtering and manipulation routines that may be convenient for PIV.

an image interrogation program resulting into estimators of particle image displacements.

validation programs to test on outliers, peak-locking effect and velocity gradients.

post-processing programs for data manipulation (flipping, rotation etc), spatial and time scaling, calculation of spatial averages and derivative quantities from the PIV data, like vorticity and strain.

miscellaneous programs and scripts to perform image format conversion, batch-processing, pipeline processing (image evaluation, validation and post-processing at once), calculation of time averages from a series of PIV data sets, data-visualization and data-manipulation.

All programs start with gpiv_.

This package contains all files used by gpivtools and gpivtools-mpi, like the man pages.

The Toolkit for Multivariate Analysis (TMVA) provides a ROOT-integrated environment for the parallel processing and evaluation of MVA techniques to discriminate signal from background samples. It presently includes (ranked by complexity):

• Rectangular cut optimisation
• Correlated likelihood estimator (PDE approach)
• Multi-dimensional likelihood estimator (PDE - range-search approach)
• Fisher (and Mahalanobis) discriminant
• H-Matrix (chi-squared) estimator
• Artificial Neural Network (two different implementations)
• Boosted Decision Trees

The TMVA package includes an implementation for each of these discrimination techniques, their training and testing (performance evaluation). In addition all these methods can be tested in parallel, and hence their performance on a particular data set may easily be compared.

This package provides development files of TMVA package for ROOT.

OpenMX (Open source package for Material eXplorer) is a program package for nano-scale material simulations based on density functional theories (DFT), norm-conserving pseudopotentials and pseudo-atomic localized basis functions. Since the code is designed for the realization of large-scale ab initio calculations on parallel computers, it is anticipated that OpenMX can be a useful and powerful tool for nano-scale material sciences in a wide variety of systems such as biomaterials, carbon nanotubes, magnetic materials, and nanoscale conductors.

CERNLIB is a suite of data analysis tools and libraries created for use in physics experiments, but also with applications to other fields such as the biological sciences.

PAW is an interactive program providing interactive graphical presentation and statistical and mathematical analysis tools. It is designed to work on objects familiar to physicists such as histograms, event files (Ntuples), vectors, etc.

The program is linked statically against the CERN libraries on 64-bit architectures in order to function properly, as its design is not very 64-bit clean.

This package includes example scripts for use by PAW or Paw++, and test scripts to make sure that the PAW or Paw++ programs behave correctly. You may run the examples and tests with the included paw-demos program.

The ROOT system provides a set of OO frameworks with all the functionality needed to handle and analyze large amounts of data efficiently.

With the data defined as a set of objects, specialized storage methods can give direct access to the separate attributes of the selected objects, without having to touch the bulk of the data. Included are histogramming methods in 1, 2 and 3 dimensions, curve fitting, function evaluation, minimization, graphics and visualization classes to allow the easy creation of an analysis system that can query and process the data interactively or in batch mode.

The command language, the scripting (or macro) language, and the programming language are all C++, thanks to the built-in CINT C++ interpreter. This interpreter removes the time consuming compile/link cycle, allowing for fast prototyping of the macros, and providing a good environment to learn C++. If more performance is needed, the interactively developed macros can be compiled using a C++ compiler.

The system has been designed in such a way that it can query its databases in parallel on MPP machines or on clusters of workstations or high-end PCs. ROOT is an open system that can be dynamically extended by linking external libraries. This makes ROOT a premier platform on which to build data acquisition, simulation and data analysis systems.

This package is a metapackage to ensure the installation of all possible ROOT packages on a system.

Octaviz is a visualization system for Octave. It is a wrapper that makes all VTK classes accessible from within Octave using the same object-oriented syntax as in C++ or Python. Octaviz also provides high-level functions for 2D and 3D visualization. Using those functions, most common visualization tasks (3D surface plots, contour plots etc) can be accomplished without any knowledge about VTK.

BLZPACK (for Block LancZos PACKage, release 04/00) is a standard Fortran 77 implementation of the block Lanczos algorithm intended for the solution of the standard eigenvalue problem Ax=µx or the generalized eigenvalue problem Ax=µBx, where A and B are real, sparse symmetric matrices, µ an eigenvalue and x an eigenvector.

The development of this eigensolver was motivated by the need to solve large, sparse, generalized problems from free vibration analyses in structural engineering. Several upgrades were performed afterwards aiming at the solution of eigenvalues problems from a wider range of applications.

Documentation: user's guide, technical report and comprehensive bibliography.
