abstract
The bibliographical compilation of stellar atmospheric parameters (Teff, logg, [Fe/H]) relying on high-resolution, high signal-to-noise spectroscopy started in the eighties with the so-called [Fe/H] catalogue, and was continued in 2010 with the PASTEL catalogue, which also includes determinations of Teff alone, based on various methods. Here we present an update of the PASTEL catalogue. The main journals and the CDS database have been surveyed to find relevant publications presenting new determinations of atmospheric parameters. As of February 2016, PASTEL includes 64082 determinations of either Teff or (Teff, logg, [Fe/H]) for 31401 stars, corresponding to 1142 bibliographical references. Some 11197 stars have a determination of the three parameters (Teff, logg, [Fe/H]) with a high-quality spectroscopic metallicity.
