Caption: Figure 2.
The average spectrum of the observations (Table 1; Section 2). The CO v = 1–0 lines (red) and the hydrogen Pfβ transition (blue) are analyzed in Section 3). A select few CO v = 2–1 lines (brown) are labeled, and their presence indicates a high temperature (Section 3.3.1). Also pointed out is the hydrogen Huϵ transition.
