Sample spectra of the TiO γ′ (0,0) and (1,1) bands illustrating the emission-dominated bands (top, red; 7 Nov. 1998), sharp absorption band-heads (middle, black; 20 Jan. 2007), and absorption bands partially filled with emission (bottom, blue; 8 Aug. 2009). The full collection of spectra is shown in Fig. C.1. Main TiO features are identified with vertical dashed lines, with black and red labels corresponding to the (0,0) and (1,1) bands, respectively.
