CELUI Is a general purpose C++ OpenGL cross-platform GUI framework that allows to create animated and rich user interfaces for simulations and games.

CMD Plot Tool calculates and plots Colour Magnitude Diagrams (CMDs) from astronomical photometric data, e.g. of a star cluster observed in two filter bandpasses. It can handle multiple file formats (plain text, DAOPHOT .mag files, ACS Survey of Galactic Globular Clusters .zpt files) to generate professional and customised plots, without the usual steep learning curve. Development using Python, OOP and a formal software development lifecycle model (Agile) allowed for the creation of an application that can be deployed on multiple systems. It works “out of the box” and does not require any installation of development environments, additional libraries or resetting of system paths. The tool is available as a single application/executable file, with the source code, on Sourceforge. Sample data is also bundled, to demonstrate its complete functionality to users. Other functionality within this application is the ability to convert DAOPHOT magnitude files to CSV format.

CRUSH is a pioneering reduction and imaging suite for many astronomical cameras operating at far-infrared, submillimeter and millimeter wavelengths, such as SHARC-2, SCUBA-2, LABOCA, GISMO, or SOFIA/HAWC+ (to name a few).

This program calculates critical curves and caustic curves for gravitational microlensing studies with an arbitrary number of stars using the analytic Witt method.

Warning: I found an error if the DR position is on the southern hemisphere. The PUB249 pdf files did not show this error and are correct (as far as I checked). All Revisions 8+ and the Windows release have been fixed. This Python TK application calculates a good set of stars for a 3 star fix, makes all calculations similar to the FAAs Celestial Computation Sheet (see FAA doc FAA-H-8083-18). Also, you can create a PDF file that generates Pub 249 Vol 1 for any epoch you specify. The PUB249 as PDF is found under "Files". I wrote this for my aircraft bubble octant :-) It is mainly useful for air navigation as it assumes a bubble sextant but may be used for normal sextants as well. Requires Ephem and ReportLab (optional for PDF output) Not to be used for real-world navigation!

Ciclope Astro is a Web 2.0 application to control an astronomical observatory (telescopes, cameras, domes, etc.). It contains other tools as album (folksonomy & votes), forum, news (RSS), karma system. Developed using the Google Web Toolkit framework.

Ciclope Planetarium is a web-based planetarium that provides a simulation of the sky from any location at any time and date. Developed using Google Maps API & AJAX. Available in PHP & J2EE. Integrated in the Ciclope Stars project (www.ciclope.info/stars)

This package can be used for further development of package needs to deal with 3D geometrical relationship. It provides class for Vector, Point, Coordinate, transformations and also provides functions for dealing with relationships between them.

Arduino al/az mount controller based on lx200 protocol.

Java program for computations with values expressed in terms of physical or other units. Supports complicated mathematical expressions and user-defined functions. Invoked from scripts, line command, or as GUI. Extensive units data base.

A set of cross-platform tools for connecting via TCP/IP to the VOEvent transient astronomy alert network. Tools include a receiver/broker, a sender/publishing tool, and a VOEvent message checker. Runs on Linux, Mac OS X and Microsoft Windows.

A client program compatible with the INDI standard (see http://indi.sourceforge.net) for remote telescope and device control. It works under Windows as well as Linux. It is writen in Python and uses the GTK in order to display the GUI.

Generate star maps for anywhere at anytime. Choose from a database of thousands of deep sky objects, including all Messier, Caldwell, and NGC objects. Also allows recording of notes on viewed objects, and configuration of user-generated observation lists.

Java library to calculate heliocentric and geocentric planetary positions. Two types of calculations are supported: a 'fast' version which has an accuracy of about 1 arc second and a 'full' version that implements the full VSOP87 theory.

A code for fast multi-dimensional density estimation . Instead of assuming an a-priori metric definition, it calculates a locally adaptive metric for each data point by using, a Shannon Entropy based, binary space partitioning scheme.

This is a parallelized algorithm performing a decomposition of the time-series data into a number of sinusoidal components, disentangling them from the white Gaussian noise. The algorithm analyses all suspicious frequencies, including the ones that look like an alias at a glance, but may become preferable later. After selection of the initial frequency candidates, the algorithm passes through all their possible combinations and estimates their multi-frequency statistical significance. In the end, it prints out the set of largest frequency tuples that were still found significant. The GPU computing is implemented through CUDA and brings a significant performance increase. It is still possible to run FreDec solely on CPU, if no suitable GPU device is available in the system. See the details of the underlying theory in Baluev 2013, MNRAS, V. 436, P. 807 The description of the algorithm itself can be found in arXiv:1309.0100. Please go to the project forum to report any bugs.

Freydis is a fork of the Eirik data exploration application. "Eirik is a tool for exploring large data sets, by using statistical analyses and multiple linked visualizations for data reduction." Freydis will continue Eirik's development.

GBTIDL provides offline data reduction for spectral line data from the GBT, a single dish radio telescope. Although the GBTIDL code is open source, running it requires you to have your own IDL license and base package.

GIRAFFE Base Line Data Reduction Software is a set of python scripts and modules and a C library to reduce FITS images produced by the Very Large Telescope (VLT) FLAMES instrument.

The GPU-BH tree solver is a FLASH4 module to calculate the gravitational potential using a CUDA device.
