    PROPER Optical Propagation Library

    Routines for wavefront propagation in IDL, Matlab, and Python

    PROPER is a library of routines for the propagation of wavefronts through an optical system using Fourier-based methods. It was developed at the Jet Propulsion Laboratory for modeling stellar coronagraphs, but it can be applied to other optical systems were diffraction propagation is of concern. It is currently available for IDL (Interactive Data Language), Matlab and Python (3.x). It includes routines for generating complex apertures and obscurations and aberrations (Zernike & PSD-defined). It includes a model of a deformable mirror for wavefront control. The routines perform near and far field propagation with automatic selection of propagators. The latest version is v3.31 released on 12 Nov 2024. Please report any bugs using the Tickets tab.

    Aciqra

    Aciqra

    A virtual planetarium for observers of the real sky.

    Aciqra is a virtual planetarium and sky mapping program which tracks celestial bodies including planets, deep sky objects and stars to an accuracy of a fraction of a degree for thousands of years into both the future and the past. It includes the 2.5 million stars of the Tycho-2 catalog supplemented by data of 120,000 stars from the Hipparcos catalog, 13,000 deep space objects from the NGC and IC catalogs and a large number of asteroids and comets from the Minor Planet Center. The program is platform-independent and can be made to work on most modern computers that support OpenGL.

    galplot

    Plot GALPROP output

    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 .

    Bugale N-Body Simulator

    Bugale N-Body Simulator

    A simple N-Body simulator.

    This project simulates the behavior, dynamics, and motion of a group of celestial objects. Given N point masses in a three-dimensional space, its present positions and velocities, and supposing that the force of attraction experienced between each pair of particles is Newtonian, the project approximately predicts it's positions and velocities at a future moment of time. The project can visualize the simulation, and create a graphic real-time output using FreeGLUT, and also have an option for textual output and archiving. Bugale N-Body Data Editor provides a graphic user interface for creating and editing the settings and body data files of Bugale N-Body Simulator. It can be found here: https://sourceforge.net/projects/bugaledataedit
