Same as Figure 4, but for source "g" alone and zoomed around the region of the CO first overtone bandhead at 22935 Å. There is an absorption component to the flux of source "g" due to young, lower mass star(s) in the ultra-compact H ii region; see the text. The positions of cool-star features due to Na i and Ca i are indicated, but not confidently detected. The rich H i Pfund series is seen to the red side of 23000 Å. Other lines are also indicated (see the text and Figure 8).
