Temperature and turbulent broadening parameter determinations using independent Doppler parameters for each species (i.e. method 2) in various components. For the weakest component (C, G and N), the uncertainties are too large to provide meaningful constraints. Black points and error bars represent the square of the total Doppler parameter b measured for various species (Fe II, S II Si II, Al II, O I and C II) as a function of the inverse of their mass. The blue line and shaded area represent the linear fit to the data and 1σ confidence band.
