These results are based on new VLT-KMOS high spectral resolution observations of 41 high-z ($1.3 \\leq$ z $\\leq 2.6$) HIIG combined with published data for 45 high-z and 107 z $\\leq 0.15$ HIIG, while the cosmological analysis is based on the MultiNest MCMC procedure not considering systematic uncertainties.
