Table 3:

Normalized velocity difference.

$\Delta V_{{\rm be}}$
HCN $(J=4 \rightarrow 3)$ -1.1
HCO $^{+}(J=4 \rightarrow 3)$ -1.2
CS $(J=7\rightarrow 6)$ -0.1

Notes. The asymmetry of line profiles is presented by the calculation of $\Delta V_{{\rm be}}$, as shown in Eq. (4), where the optically thin species correspond to H13CO+ for HCO+ and H13CN for HCN and CS. The values used to compute the blue excess are taken from Gaussian fits to the corresponding spectra.
