Perseid meteor spectrum at OHP

Spectroscopy workshop at OHP Every year, a spectroscopy workshop is held at the site of the Observatoire de Haute Provence, where around 50 spectroscopists, beginners and experts, meet for a workshop with lectures during th day and observing during the night (www.shelyak.com/ohp-spectro-star-party-2019). I used this opportunity to record meteor spectra in a clear sky and … Continue reading Perseid meteor spectrum at OHP

Meteor spectra analysed with Python

Summary This manual explains the use of a Python script for the analysis of video meteor spectra. The theory behind it has been described in (Dubs and Schlatter, 2015): meteor_spectroscopy_wgn43-4_2015.pdf). Until now, the method had been applied successfully to analyse meteor spectra obtained with high sensitive video cams such as the Watec 902 H2 ultimate … Continue reading Meteor spectra analysed with Python

M20171209 spectrum by Koji Maeda analysed

  Meteor Spectrum Calibration Example Introduction Meteor spectra can give a lot of information about the meteor, such as composition and temperature. However, for amateurs the calibration of the spectra is not easy. Here a method is given for grating spectra recorded with a video camera, which produces linear spectra with constant dispersion. The method … Continue reading M20171209 spectrum by Koji Maeda analysed

Unified python script for calibration and processing of meteor spectra

In my previous post meteor-spectroscopy-python-scripts-on-github I have presented two scripts. One for the laser calibration of meteor spectra, which determines the parameters for the orthographic transformation, which is used to linearize meteor spectra. The other script was used for the processing of meteor spectra. These scripts have now been combined into a single script which … Continue reading Unified python script for calibration and processing of meteor spectra

Meteor spectroscopy Python scripts on Github

In previous posts I have described the analysis of meteor spectra with different methods, first using conventional software then with dedicated Python scripts. Lately I have added a windows graphical user interface (GUI), which simplifies the analysis of meteor spectra (https://meteorspectroscopy.org/2020/03/27/meteor-spectra-analysis-new-version/). Now that the scripts have been tested I made them publicly available at Github … Continue reading Meteor spectroscopy Python scripts on Github

Meteor spectra analysis, new version

Introduction Some time ago I presented a python script for the analysis of meteor spectra. It worked as a pipeline, accepting input in a line by line form for the various parameters. It was described here (https://meteorspectroscopy.org/2018/11/18/meteor-spectraanalysed-with-python/ , referenced as m_pipe62). In the meantime it has been improved with a windows graphical user interface (GUI), … Continue reading Meteor spectra analysis, new version
