Notes. Numbers in parentheses are 1σ uncertainties in units of the last digits. Line parameters obtained by Gaussian fits to the line profiles.

(a)

Intensity diminished due to overlap with frequency switching artifact.

(b)

Rest frequency of transition 51,5−41,4 of E species constrained to 84 151.52 ± 0.03 MHz by fixing VLSR.

(c)

Line blended.
