Notes.

1

Quantum numbers are - JKa,Kc.

a

Observed frequency of the transition assuming a LSR velocity of 5.83 km s−1.

b

Integrated line intensity in mK km s−1.

c

Linewidth at half intensity derived by fitting a Gaussian function to the observed line profile (in km s−1).

d

Antenna temperature in millikelvin.

A

Frequency switching data with a throw of 10 MHz only. Negative feature present in the data with a 8 MHz throw.

B

Frequency switching data with a throw of 8 MHz only. Negative feature present in the data with a 10 MHz throw.

C
