Comparison of input labels with values recovered by LRPayne from fitting multiple synthetic spectra at different S/N (green: S/N = 20, red: S/N = 100 and black: S/N = 1000). Only 14 elements (O, Na, Al, Mg, Si, Ti, Ca, Mn, Cr, Ni, V, Sc, Ba, and Y) have been validated using observed data (See Section 3.2.2). For other elements, this result represents the upper limit of LRPayne sensitivity.
