FASMA is a tool to analyze stellar spectra as described in Andreasen et al. 2016 and Tsantaki et al. 2017 (in prep. for the synthesis). FASMA comes with four different drivers to analyze a spectrum, all described below in detail.
Any questions, issues, or suggestions are encouraged. See contact for details in how to get in touch with us.

Citation

Please cite the papers mentioned above if you use FASMA in your research. We are also interested in seeing non published research, so we can improve FASMA for a larger group of researchers.

Drivers

There are four different drivers: EW, EW method, synthesis method, and abundances described below. When hovering the mouse over the options, a small description will appear.

• EW for measuring EWs from a spectrum. Uses ARES in the background.
• EW method for getting atmospheric parameters from the measured EWs.
• Abundance for obtaining abundance of different elements. Atmospheric parameters are needed for this step.
