Notes.

(a)

In Paper I, we derived the value N(N2H+) ≈ 0.91 ± 0.01 × 1013 cm-2 from observations of N2H+(1−0) emission, which is in good agreement with the present value.

(b)

The principal velocity component was not detected.

(c)

Calculated by using the optically thin approximation.

(d)

The associated error is larger than the value.
