Multi-platform Variable Star Visualisation and Analysis
VStar is a multi-platform, easy-to-use variable star observation visualisation and analysis tool. Data can be read from a file or the AAVSO database, light curves and phase plots created, period analysis performed, and filters applied. Plugins can be developed, e.g. to make additional observation sources available.

Echoes it's a radio spectral analysis software for RTL-SDR devices,
Echoes it's a radio spectral analysis software for RTL-SDR devices, designed for meteor scattering purposes. RTL-SDR are very cheap Software Defined Radios that uses DVB-T TV tuner dongles based on Realtek's RTL2832U chipset. Echoes doesn't demodulate neither decode any human-made signal. Its main goal is to analyze and record the total power of natural signals and generate screenshots and tabular data (CSV, GNUplot) output in presence of particular peaks in a selected narrow range of frequencies. Since there is no demodulation, there is no provision for audio listening, except for a notify sound when an event has been recorded.
The PDL module gives standard perl the ability to COMPACTLY store and SPEEDILY manipulate the large N-dimensional data sets that are the bread and butter of scientific computing.
General data-reduction tool for fiber-fed integral-field spectrographs
p3d is a general data-reduction tool for use with fiber-fed integral-field spectrographs (IFSs); although, the spectrum viewer works with spectrum data cubes of any origin. The tool is built about the proprietary software IDL (Harris/EXELIS; see http://www.harrisgeospatial.com), but can be used without any license. Most slowly running loops are implemented in parallelized C (OpenMP).
Fortran library to compute positions of celestial bodies
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
RFI detector and quality analysis for astronomical radio observations
The AOFlagger is a tool that can find and remove radio-frequency interference (RFI) in radio astronomical observations. The code has been highly optimized for speed and accuracy. It is used by default for the LOFAR radio telescope and thus is in productional stage. The software can run in a fully automated way, but a graphical interface is provided to analyse results and tweak the strategy. The preferred input file format is the Casa Measurement Set (MS) format. I believe that the AOFlagger is the best available flagger, both in terms of accuracy and speed. It has been succesfully used on several interferometric telescopes, including LOFAR, WSRT, VLA, GMRT, ATCA and MWA, and the single-dish telescopes Parkes and Arecibo 305m. Besides the flagger, the software consists of tools to efficiently visualize data in different ways, such as plotting time-frequency diagrams and power spectra. It provides the programs rficonsole, rfigui, aoqplot, aoquality and more.
Astronomy CCD capture software
A CCD capture software intended for the amateur astronomer. It include all the features required to perform digital imaging CCD observation of celestial objects. Using the standard drivers protocol INDI and ASCOM it can connect and control the CCD camera, the focuser, the filter wheel and the telescope mount. This software is part of a full suite for astronomical observation: https://sourceforge.net/projects/skychart/ https://sourceforge.net/projects/indistarter/ https://sourceforge.net/projects/eqmodgui/ Requirement: https://sourceforge.net/projects/libpasastro/ See also: https://sourceforge.net/projects/indi/

WSClean is a fast widefield interferometric imager
WSClean (w-stacking clean) is a fast generic widefield imager. It uses the w-stacking algorithm and can make use of the w-snapshot algorithm. As of Feb 2014, it is 2-12 times faster than CASA's w-projection, depending on the array configuration. It supports full-sky imaging and proper beam correction for homogeneous dipole arrays such as the MWA. WSClean allows Hogbom and Cotton-Schwab cleaning and has wideband, multiscale, compressed sensing and joined-polarization deconvolution modes. All operations are performed on the CPU.

Software for polar alignment of equatorial mounts
PARot is a program for ultra fast and precise polar alignment of equatorial mounts. You can easily achieve alignment accuracy better than 1 arcmin in 5 minutes of time. You take one image of the celestial pole, rotate the mount around the RA axis and take another image. The program compares the images and shows you the necessary adjustment. The adjustment process is controlled by the live-liew created by your camera. Requirements: * A computer with Windows OS (tested with WinXP x64, Win7 x64, Win7 x86). * Maxim DL version 5. * A camera which can be controlled from MaxIm. * A combination of telescope and camera such that the camera can 'see' a star in any field with the exposure time of a few seconds. * A view of the celestial pole. It can't be blocked, e.g., by ground objects. * Read the manual please!
A library containing Some Useful Fortran Routines
libSUFR contains Some Useful Fortran Routines that I wrote for my own use, but that may also be useful for others. At the moment, it also "SUFRs" from the fact that Fortran module files are compiler-dependent...
Astrophysical magnetic fields simulator
Hammurabi is a HEALPix-based tool for simulating observables such as polarized synchrotron and thermal dust emission from models of physical inputs such as magnetic fields, dust and electron distributions, etc. It is a modular C++ framework into which you can add your own models easily and then use it to perform the line-of-sight integration to compute the observables. See the wiki for installation and usage information. Please cite the original Waelkens et al. (2009) paper if you use hammurabi. Hammurabi is being re-written and significantly improved.
