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.

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.

The GALPROP program (http://galprop.stanford.edu) computes cosmic-ray propagation numerically. To obtain manifestly accurate solutions an explicit method is now available to replace the Crank-Nicolson operator-splitting method. This can be implemented in the public version of GALPROP with the update provided here. Instructions: replace the four files propel.cc, propel_diagnostics, Galdef.cc and Galdef.h and rebuild the executable. Add solution_method and solution_convergence to the galdef parameter file. A test GALDEF file with these parameters is galdef_54_reltest09; the diagnostics document the accuracy of the solution. A full explanation is given in the GALPROP Explanatory Supplement http://www.mpe.mpg.de/~aws/galprop_explanatory_supplement.pdf Thanks to Deepak Khurana for requesting and testing this update. Now replaced by this project: http://sourceforge.net/projects/galprop where further updates can be found.

DualSPHysics is based on the Smoothed Particle Hydrodynamics method and can be downloaded from the official website (www.dual.sphysics.org). The code is developed to study free-surface flow phenomena where Eulerian methods can be difficult to apply, such as waves or impact of dam-breaks on off-shore structures. DualSPHysics is a set of C++, CUDA and Java codes based on the SPHysics FORTRAN project (www.sphysics.org) that are designed to deal with real-life engineering problems and are provided along with pre-compiled binaries and source for Windows/Linux/Unix as well as a number of example test cases.

Galaxia is a code for generating a synthetic model of the galaxy. The input model can be analytical or one obtained from N-body simulations. The code outputs a catalog of stars according to user specified color magnitude limits.

This project contains two packages. An Orbital Mechanics Study developing the physics equations related with satellite tracking and a libtool C++ library to encapsulate the satellite tracking calculations (gsat).

RTS2 is project to create an open source environment for control of a fully autonomous observatory. It is running about dozen fully autonomous observatories. Its modular design allow easily addition of new devices (to already huge supported HW list).

Plot package for GALPROP https://sourceforge.net/projects/galprop Plots models and data for cosmic-ray spectra, secondary/primary ratios, gamma rays, synchrotron. Includes gamma-ray source population synthesis and corresponding plots. For gamma rays, convolves models with the Fermi-LAT response. This release is to assess interest. It requires many input data files (not included) which will be made available as required. With the data provided cosmic-ray spectra and ratios and source population synthesis will work. Uses CERN root package. See README for details. Plots produced with GALPLOT can be seen in http://arxiv.org/abs/1101.1381 http://adsabs.harvard.edu/abs/2011A%26A...534A..54S http://adsabs.harvard.edu/abs/2011ApJ...739...29B and http://arxiv.org/abs/1309.2947, published version: http://mnras.oxfordjournals.org/content/early/2013/10/03/mnras.stt1718.abstract .
