摘要：We have noticed two typos in our original paper. In Sect. 3.1,
Eq. (2), which gives the expression of the effective temperature
of an ion-neutral reaction, should read (Pineau des Forêts et al.
1986)
T eff =
m 1 T 2 + m 2 T 1
m 1 + m 2
+
1
3k
m 1 m 2
m 1 + m 2
u 2
D .
(2)
In Sect. 5.2, the destruction timescale of the CH + by reaction
with H 2 should read ∼1 yr f −1
H 2
(50cm −3 /n H ). These correct
expressions are those that have been used in all the calculations
performed in our original paper. These typos have therefore no
bearing on the paper results/conclusions.
