Example of spectra in the visible region, used to fit the atmospheric parameters, of eight selected stars from the FSR 1776 cube (black lines) and the best fit template spectrum from the MILES library (red line). For each combination of these two parameters (text on the left with the approximate T_eff and log(g)) a pair of spectra is shown with higher and lower S/N and magnitude, all with similar [Fe/H]∼ + 0.1. From top to bottom, in order of increasing surface gravity and temperature, the pairs represent the RC, lower RGB, SGB, and MS turnoff.
