Several important improvements were implemented in this new version:

  • iSpec now uses the SPECTRUM capabilities to compute synthetic spectra with hyperfine structure and isotopes
  • Alpha elements are automatically enhanced when the analysed stars are metal poor. It follows the standard mixture of the MARCS model atmosphere.
  • A complete automatic pipeline based on iSpec (synthetic spectral fitting technique) is released as an example (included in the virtual machine too).


iSpec is released for the first time to the scientific community. Detailed description in Blanco-Cuaresma et al. 2014.
