DAOSPEC is a Fortran code written by P. B. Stetson. It finds absorption lines in high-quality stellar spectra and then it estimates the stellar radial velocity and the equivalent widths of identified lines. Its main strength is that it is able to deblend lines to a certain extent and to statistically take into account the line blanketing effects of tiny unresolved lines in the computation of the stellar continuum. It can be run through wrappers such as 4DAO or Doop, written by other colleagues. To obtain a copy of the code, you can contact P.B. Stetson and he will send you the files once you have compiled a standard agreement form.

Gala is a fortran code to derive spectral parameters using the equivalent width method. It was written by A. Mucciarelli as an optimizer that relies on the WIDTH code originally developed by R.L. Kurucz. It can use different atmospheric models and it produces a variety of useful outputs to check the quality of the results. Gala was estensively tested within the Gaia-ESO survey project, to derive abundances of thousands of spectra automatically.
