    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 v3.3.1 (IDL & Matlab) and v3.3.4 (Python). Please report any bugs using the Tickets tab.

    Celestial Precomputation

    Celestial Precomputation

    Sight Reduction for Air Navigation with Python

    Warning: I found an error if the DR position is on the southern hemisphere. The PUB249 pdf files did not show this error and are correct (as far as I checked). All Revisions 8+ and the Windows release have been fixed. This Python TK application calculates a good set of stars for a 3 star fix, makes all calculations similar to the FAAs Celestial Computation Sheet (see FAA doc FAA-H-8083-18). Also, you can create a PDF file that generates Pub 249 Vol 1 for any epoch you specify. The PUB249 as PDF is found under "Files". I wrote this for my aircraft bubble octant :-) It is mainly useful for air navigation as it assumes a bubble sextant but may be used for normal sextants as well. Requires Ephem and ReportLab (optional for PDF output) Not to be used for real-world navigation!

    Astrophotography Lab

    Astrophotography Lab

    A collection of useful tools for astrophotographers

    Astrophotography Lab (APLab) is a free program intended for anyone interested in astrophotography. It has two main purposes: - Interpreting data extracted from your astrophotos to produce useful information. - Using this information as a help for further improving your imaging results. The program consists of four main tools: an analyser tool, a calculator tool, a simulator tool and a plotting tool. The tools are connected, allowing you to transfer information between them, and easily go all the way from measuring your camera's sensor to finding the optimal settings for your next imaging session. APLab supports a wide range of CCD and DSLR cameras and telescopes by default, and you can easily add the necessary information for your own equipment. Check out the home page (linked to below) for more information and download links.

    CMD Plot Tool

    CMD Plot Tool

    Calculates and plots Colour Magnitude Diagrams from Astronomical data

    CMD Plot Tool calculates and plots Colour Magnitude Diagrams (CMDs) from astronomical photometric data, e.g. of a star cluster observed in two filter bandpasses. 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. Sample data is also bundled, to demonstrate its complete functionality to users. Other functionality within this application is the ability to convert DAOPHOT magnitude files to CSV format.

    FABS

    FABS

    Fluorescence and absorption spectroscopy made easy

    FABS is a program designed to run a fluorescence/absorption spectrometer on Windows. The program analyzes spectra and provides graphs and data files. Users may choose to input video files from cell phones or other cameras, still images, or even live streams of video from webcams. FABS can perform any necessary calibration and image preprocessing. Experienced users have a number of more advanced options such as background subtraction, adjustments for nonlinearities in detector response, and graph smoothing. FABS was designed with students in mind, as a way to help high schoolers and undergraduates learn about spectroscopy without paying for expensive equipment and software. Accompanying this software is a hardware design, which can be used as a bare-bones spectrometer that will provide quantitative absorption and fluorescence emission spectra at an extremely low cost. It uses only materials that many people can find around their home.
