CO J = 3−2 spectra (blue solid) obtained from the peak pixel of each position where we detected CO, compared to the H i spectra (red dashed) at those positions. In each case the spectra have been smoothed to Δv = 10 km s^-1 and the H i profile has been scaled to fit the CO peak (pointed out with an arrow at each position). No spatial smoothing was applied. The green dashed lines mark the σ ~ ± 0.04 K average level (see Table 2). The positions labeled are the same as in Figs. 3 and 4.
