Caption: Figure 2.
The two panels show Δχ2 as a function of parent scale length (Lp) of HCN for November 5 (left) and 21 (right). The black line connects the discrete Δχ2 points to guide the eye. Dotted horizontal lines indicate the Δχ2 = 1 threshold (1σ, 68% confidence), while dashed horizontal lines mark the Δχ2 = 6.63 threshold (2.6σ, 99% confidence).
