Cactus is a general, modular, parallel environment for solving systems of partial differential equations. The code has been developed over many years by a large international collaboration of numerical relativity and computational science research groups and can be used to provide a portable platform for solving any system of partial differential equations.
Gpredict is a real time satellite tracking and orbit prediction program. Besides the general orbital data for satellites, gpredict can also calculate the footprint, visibility, doppler shift, signal loss, and signal delay for each satellite relative to one or more ground stations. The calculated data can be viewed in tables, on maps, or on polar graphs.
SaVi is satellite visualization software that lets you create, run, examine, and modify satellite orbits in two and three dimensions. Simulations of Iridium, Globalstar, Galileo, GPS, and other satellite constellations are included. SaVi requires Tcl and Tk on a system with Unix libraries. SaVi works well with the 3D renderer Geomview. Geomview is optional, though recommended for its 3D rendering capabilities.
GCX provides a complete set of data-reduction functions for CCD photometry, with frame WCS fitting, automatic target identification, aperture photometry of target and standard stars, single-frame ensemble photometry data reduction, multi-frame color coefficient fitting, extinction coefficient fitting, and all-sky photometry. It also controls CCD cameras and telescopes, and implements automatic observation scripting. Cameras are controlled through a hardware-specific server, to which gcx connects through a TCP socket. The program can control telescopes which use the LX200 protocol, and refine pointing by matching images to the GSC catalog position of stars. It generates FITS files with comprehensive header information.
GraphPak is a programming library of 2D and 3D charting objects for the Qt toolkit. It provides software developers with a set of C++ objects to easily create charts or graphs that aid in the visual presentation of technical and business data. This release includes Bar, Line, Pie, Ring, Area, Hi-Lo, Box and Whisker, and Polar charts. It is based on the KD Chart product from Klarälvdalens Datakonsult AB.
ESO-MIDAS (European Southern Observatory Munich Image Data Analysis System) provides general tools for image processing and data reduction with an emphasis on astronomical applications, including imaging and special reduction packages for ESO instrumentation at La Silla and the VLT at Paranal. It also contains an applications packages for stellar and surface photometry, image sharpening and decomposition, statistics, and more.
FTOOLS is a highly modular collection of over 200 utilities for processing and analyzing data in the FITS (Flexible Image Transport System) format. Each utility performs a single simple task such as the presentation of file contents, extraction of specific rows or columns, appending or merging tables, binning values in a column, or selecting subsets of rows based on a boolean expression. It provides both generic processing and analysis utilities and utilities specific to high energy astrophysics data sets used for the ASCA, EINSTEIN, ROSAT, GRO, VELA5B and XTE missions.
