Typical sample spectra for stars with different T_eff (mem0704: 4330 K, rgb0522: 4220 K, mem0631: 4035 K, mem0604: 3730 K, mem0606: 3640 K) are shown to illustrate how molecular features change as a function of T_eff. The spectra have been offset at arbitrary fluxes. The three coolest stars in this sample have similar, relatively high metallicities (–0.82, –0.74 and –0.62 dex) while the two hottest stars are metal-poor (–2.55 and –1.87 dex).
