Examples of spectral fitting carried out with ETOILE for a metal-rich (NGC 6528_11), an intermediate-metallicity (NGC 6558_7), and a metal-poor (Terzan8_11) star in the upper, middle, and bottom panels, respectively. The left panels represent the best fits using MILES template spectra, the right panel the best fits using Coelho spectra. Stellar spectrum (black line) is overplotted by the template spectrum (red line) that best fits it. The residuals of each fit are presented below each stellar spectrum. The match between the spectra is made following the procedures explained in Sect. 3.2. The fit is very satisfactory for the whole wavelength interval for all cases. In each comparison we give the parameters of the template spectrum and of the average parameters using only MILES or only Coelho spectra for each star, as presented in Table 6.
