  • One of the main deliveries of spectroscopic surveys are the stellar parameters and abundances that are determined from automatic pipelines. In this talk I will present 2 important sets of stars that have been used to validate and calibrate the astrophysical parameters of not only several spectroscopic surveys but also Gaia DR2 parameters from the BP/RP spectra. These are the Gaia benchmark stars and a sample of solar twins, both developed by our group at the Astronomy Nucleus in Chile. I will discuss our current activities and future plans for the next generation of spectroscopic surveys and further data releases of Gaia.
