...Since there is no demodulation, there is no provision for audio listening, except for a notify sound when an event has been recorded. Finally, Echoes can also operate getting an audio input, thus producing audio spectra. This way, Echoes can also be used with traditional receivers.

...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.

ChiantiPy is a Python package for the CHIANTI atomic database for astrophysical spectroscopy. It provides access to the database and the ability to calculate various physical quantities for the interpretation of astrophysical spectra.

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,...

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. ...

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 in user-defined bands. A sample user program is provided which can be edited to provide the required functionality. See also http://sourceforge.net/projects/galprop, which includes more models.

ComaGUI was developed as a part of my Master Thesis at the University of Vienna. It is a graphical user interface for the Fortran SW COMA (Copenhagen Opacities for Model Atmospheres: from Aringer (2000) ) which can generate synthetic AGB-star spectra.

AGBStarViewer is an astronomical SW which was developed as a part of my Master Thesis at the University of Vienna. It is designed to compare star spectra and obtain best fits of many hundreds spectra. Licence: GPLv2

a program to retrieve magnetic power spectra from Faraday rotation maps using a method described in http://arxiv.org/abs/0912.3930

Educational astrometry utility for plotting stars on a Hertzsprung-Russel diagram. Useful for learning about stellar spectra and properties and performing spectroscopic parallax calculations, as found in many high school physics courses.

For the direct and detailed analysis of supernova spectra.

The aim of Stellar Population Spectrum Fitting (SPSF) is to collect different methods for fitting observed with a synthetic spectra.

Feature extraction toolkit based on a wavelet multiscale vision model. Includes 1D signal processing sample application for line identification and classification of astronomical spectra.

The 'BandSystem' spectral analysis system is a rule-based system for the classification of mineral spectra. It consists of a preprocessor, a feature extractor, and a rule-based system to identify minerals from infra-red reflectance spectra.
