iSpec has been updated thanks to the contribution of several users:

  • Bug fix: Parameter determination not working properly from the visual interface
  • Bug fix: SME spectra was not correctly re-sampled before applying convolutions
  • MOOG now always computes molecular equilibrium for the most important species
  • Air <-> Vacuum conversion changed to follow IAU standard and VALD3


iSpec now supports several radiative transfer codes: SPECTRUM, Turbospectrum, SME, MOOG and SYNTHE/WIDTH9.


The Gaia Science Alerts reported in mid-september 2016 three supernovae candidates (among many others) that we observed and confirmed with mercator telescope: Gaia16bic, Gaia16bib and Gaia16biv. The first one is one of the most beautiful SN I have ever observed:


I observed the near earth object (NEO) 410777 2009FD from the Mercator telescope. It was so exciting that I built this animation where we can see it crossing the sky:


New version with only minor bug fixes such as:

  • Continuum fit was failing when the user has the latest version of the python dependencies.
  • The "Find line masks" option from the visual interface was not working.
  • The pre-processing stage of the iSpec pipeline failed when run in parallel.
