X-Bc (formerly: xbc) is a graphical user interface to the command line calculator bc. All Inputs and Outputs stays visible for editing and comparing. Functionality: trigonometry, number-theory, exponential funcs, scientific constants, primenumbers ...

chklinks is a non-threaded Perl link checker. It helps finding broken links on your website. It does not raises many simultaneously connections for its job, run out of the resources and crash your system in a moment.

libTheSky is a Fortran library to compute positions of celestial bodies (Moon, planets, stars) and events (conjunctions, eclipses). It forms the core of the software that produces the Dutch popular-astronomy website http://hemel.waarnemen.com

Implementation in Python of some of the statistical methods provided by "asurv", the survival analysis software.

The goal of spacesim is simulation of a battles in free space. Unlike other such games, spacesim models management of the ship from the point of view of the captain, instead of the pilot. It allows management of the ship of several players at one time.

The Automated Parameter Estimation and Model Selection Toolkit is a fast, parallelized MCMC engine written in C for Bayesian inference (parameter estimation and model selection).

Library of Java code to interact with the data-recording formats (RPFITS and PSRFITS) used at the Australia Telescope National Facility (ATNF). It also provides tools for extracting metadata from the files for supply to Virtual Observatory instances.

This project contain application to extract images from arch.H format used by Asteroid Data Hunter, and also compiled releases of updated versions of Asteroid Data Hunter itself.

With this tool you can manage your equipment and plan and log your observations. You can create a logbook (as a PDF) from your logged observations.

Multiplatform and Open Source project for astronomical image processing

CometCube - software that used to analyze datacube(FIT format) obtained from radio telescope. This project is using IDL evironment and language.

Control Applications for Astronomical CCD Cameras

AstroPhp is a library of functions useful for astronomy calculations writen in PHP.

Automated supernova finder is a software package to automatically compare FITS images to a nominated reference image with the aim of finding supernovae or other optical transient phenomena.

Open source tool to assist with study of Astronomy, Astrophysics and Cosmology. To include usefull data and calculation of common equations used in the basic study of these subjects. Later versions may interface to other existing Astronomy software t

A Bayesian analysis of neutron star mass and radius observations based on O2scl.

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

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 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.

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.
