Notes. The error bars in Nl include errors due to both uncertainty in the continuum level and the line-fitting procedure. The velocity components are as follows: component 1: vcen = −0.68 ± 0.02 km s-1, ΔV = 1.85 ± 0.51 km s-1, component 2: vcen = −2.85 ± 0.04 km s-1, ΔV = 0.86 ± 0.08 km s-1, and component 3: vcen = −4.2 ± 0.2 km s-1, ΔV = 1.4 ± 0.4 km s-1. Velocity component 3 is detected only above the noise level in P(4) and Q(4).
