The method of using an orthographic transformation to linearize spectra is getting used more frequently. A research group from the Beijing National Observatory of Space Environment in China has used the method for the analysis of video meteor spectra and is publishing the results now. Sipeng Yang et. al., MIOS optical subsystem for determining physical … Continue reading New publication about meteor spectroscopy
Meteor spectra 2020
Just like the year before (meteor spectra 2019 ), I put together the spectra recorded in 2020 in a list: meteor-spectra-2020Download The equipment and the processing of the spectra is the same as before, so it is not repeated here, just an example:
Update for meteor spectra processing with Python
Instrument Response In a previous blog I have described a Python script with a GUI for calibrating and processing meteor spectra. The spectrum calibrated in wavelength is still not the final result of the processing. One would like to have a plot of energy against wavelength. Unfortunately the measured intensity is influenced by detector sensitivity, … Continue reading Update for meteor spectra processing with Python
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
