    PROPER Optical Propagation Library

    Routines for wavefront propagation in IDL, Matlab, and Python

    ...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 v3.3.5.

    Tables of the Sun

    A Re-implementation of Newcomb's Theory of the Sun

    Simon Newcomb published his theory, known as Tables of the Sun, in 1898. It was used by the American Ephemeris and the Astronomical Almanac into the 1980's to compute the daily positions of the Sun. This Theory is a semi-analytic model which expresses quantities as a trigonometric series with numerical coefficients. This type of model produces a compact computer function which has enough accuracy to be useful to most users. My goal is to create a model using C which will reproduce exactly the results published in the Astronomical Almanac for the years 1981, 1982 and 1983.

    CMD Plot Tool

    CMD Plot Tool

    Calculates and plots Colour Magnitude Diagrams from Astronomical data

    ...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. ...

    stellarics

    Inverse Compton emission from heliospheres of sun and stars

    Cosmic ray electrons scatter on the photon fields around stars, including the sun, to create gamma rays by the inverse Compton effect. This program computes the spectrum and angular distribution of this emission. The software also includes general-purpose routines for inverse Compton scattering on a given electron spectrum, for example for interstellar or astrophysical source modelling. For further information see these publications: http://arxiv.org/abs/astro-ph/0607563,...

    hadronic gamma rays

    gamma rays from hadronic processes in astrophysics

    Cosmic-ray hadronic interaction matrices for gamma-ray and other secondaries for an interstellar medium target are available as described in Huang et al. Astroparticle Physics, 27, 429 (2007). These require significant effort in practice to compute emissivities for given input spectra. To supplement these matrices I provide here a C++ class which reads the matrices, interpolates on user-defined particle and gamma-ray energy grids, and computes the gamma-ray emissivity either differential or...
