Mopra beam efficiencies.

Source Line Mopra efficiency

IRAM 04191 N2H+ 1−0 0.25 ± 0.01
IRAM 04191 CS 2−1 0.35 ± 0.02
IRAM 04191 C34S 2−1 0.52 ± 0.13
IRAM 04191 H13CO+ 1−0 0.36 ± 0.03
OPH A SM1N N2H+ 1−0 0.36 ± 0.003

Notes.Mopra efficiencies derived after comparing independent observations from the IRAM 30 m and Mopra telescopes. The IRAM 30 m spectra were smoothed to the Mopra angular resolution.
