Spectroscopy

All spectra are processed with SpcAudace a spectra reduction and analysis software developed since 2004 by Benjamin Mauclaire. Based on AudeLA, it runs under Microsoft, GNU/Linux and MacOS X, in French and English. It offers an automatic approach to spectrum reduction via powerful pipelines. It takes the user from pre-processing to the production of the line profile calibrated and corrected for various deformations to be ready to use in a web page (PNG file) or in a database such as BeSS. Its astrophysical functionalities allow you to easily exploit the scientific information contained in your spectra.
