    PROPER Optical Propagation Library

    Routines for wavefront propagation in IDL, Matlab, and Python

    NOTICE: PROPER will stop being supported at the end of 2026. It will remain available on Sourceforge after that, but there will be no updates or bug fixes. 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 v3.3.5.

    libnexstar

    C API to control NexStar compatible telescopes

    This library implements the serial commands supported by the Celestron NexStar hand control (HC) and SkyWatcher/Orion SynScan HC. This applies to the Celestron: NexStar GPS, NexStar GPS-SA, NexStar iSeries, NexStar SE Series, NexStar GT, CPC, SLT, Advanced-VX, Advanced-GT, CGE, CGEM etc. SkyWatcher: EQ5, HEQ5, EQ6 (Pro), AZ-EQ5 GT, AZ-EQ6 GT, EQ8 etc. and the corresponding Orion mounts. Communication to the hand control is 9600 bits/sec, no parity and one stop bit via the RS-232 port on the base of the hand control. Communication can be established over TCP/IP if nexbridge is running on the computer connected to the telescope. To control network based telescopes nexbridge must be used on the remote site. https://sourceforge.net/projects/nexbridge/

    AOFlagger

    AOFlagger

    RFI detector and quality analysis for astronomical radio observations

    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

    WSClean is a fast widefield interferometric imager

    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.

For extended example how to use this perl module look in to the distribution folder for nexstarctl.pl. This program is a complete console tool to control NexStar telesctopes based on NexStarCtl module. To control network based telescopes nexbridge must be used on the remote site. https://sourceforge.net/projects/nexbridge/

    gcr_convert

    converts cosmic-ray files from GALPROP for viewing / plotting.

    The GALPROP program (http://galprop.stanford.edu) computes cosmic-ray propagation in the Galaxy, in 2D or 3D. The ouput cosmic-ray distribution is in the form of FITS files which however are not convenient for viewing or plotting with the standard ftools program fv, since the files have 4 or 5 dimensional arrays (due to the momentum and species axes) while fv handles only 3 dimensional arrays. This program converts to fv-compatible FITS files, either from 2D to (R,z) or from 3D to (x,z) at y=0 or (x,y) at z=0, in each case for a chosen cosmic-ray species. The third axis is momentum in each case. The distribution can be viewed with fv as a colour image, contoured, output to a file etc. The program is stand-alone and requires only the cfitsio library to be installed. Build instructions are in the program header. The FITS.cc/FITS.h class used provides simple convenient access to image data, useful also for other projects. For fv and cfitsio see http://heasarc.gsfc.nasa.gov/fitsio
