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. -

U-Net Fusion RFI
U-Net for RFI Detection based on @jakeret's implementation
...The primary improvements to this code base include a training and evaluation framework, along with a fusion based approach to detection, combining a number of models (currently hard coded to two trained models) along with Sum Threshold as an additional "expert." Additional work is being done to add custom layers to this model for further experimentation, including Squeeze/Excitation layers (unimplemented.) Sum Threshold (in fusion as an expert, and in testing as a comparison) requires the use of AOFlagger by Andre Offringa. You can find this code at https://gitlab.com/aroffringa/aoflagger. This project will use the aoflagger program within the code, so you may need to ensure that any environment variables are set for aoflagger before use. ... -

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,... -

INDI alignment infrastructure
N point alignment infrastructure for INDI telescope drivers
...This layer performs transformation services for telescope coordinates as they pass up and down to the underlying driver. The conversion matrices are computed from alignment datums passed down into the alignment layer. The N point alignment model can be used for both equatorial and alt azimuth mounts. The alignment database and coordinate conversion functionality is isolated in a separate class library module which can also be used to provide this functionality directly to INDI telescope drivers. -

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... -
