BACCHUS
Brussels Automated Code for Characterizing High accUracy Spectra
The BACCHUS code (T. Masseron, T. Merle & K. Hawkins 2016ascl.soft05004M), originally developed at ULB, is intended to automatically perform 1D LTE stellar spectroscopy for one to thousands late-type stars. Three modes are possible:
- simple elemental abundance analysis (
bacchus.abundmodule) - precise equivalent width measurements (
bacchus.eqwmodule) - determination of stellar parameters (
bacchus.parammodule)
The BACCHUS code is based on:
- the 1D LTE radiative transfer fortran code Turbospectrum (2012ascl.soft05004P)
- the MARCS model atmosphere grid (2008A&A...486..951G)
- the model atmosphere interpolation fortran code (https://marcs.astro.uu.se/software.html)
- cshell scripts
- the SuperMongo plotting software (http://www.astro.princeton.edu/~rhl/sm)
WARNING It is the responsability of the user to get the proper rights for the use of the SuperMongo plotting software.

/!\ Warning:
- for compilation of interpol_modeles.f with gfortran, use the option -std=legacy
- the ls command should not be redefined (e.g. with an alias) using the -F option (for example in the ~/.tcshrc)
