Note: Cols. 2-10 indicate energy level transitions, line emission frequencies, half power beam width (HPBW), instrument (30 m for IRAM-30 m and Mo for Mopra telescope), main beam efficiency $\eta_{\rm mb}$, receiver name, velocity resolution $\delta \varv$, observation mode, and system temperature $T_{\rm sys}$.
a RaM - Raster Map mode set to create a 3 $\times $ 3 pixels mini-map with a $\Delta\theta$ step of 10 $^{\prime \prime }$ around source emission peak.
b RaM2 - Raster Map mode with HERA receiver, set to create a 190 $^{\prime \prime }$ $\times $ 140 $^{\prime \prime }$ map with a $\Delta\theta$ step of 6 $^{\prime \prime }$ towards MM1, MM2, and MM3.
c OTF - On-The-Fly observing mode carrying out on a 5$^\prime$ $\times $ 5$^\prime$ grid with an angle step $\Delta\theta$ of 9 $^{\prime \prime }$ and an OFF position at 30$^\prime$ from the center.
d Conversional factor is $S/T_{\rm mb}=4.95$ Jy/K for IRAM 30 m telescope and $S/T_{\rm mb}=22$ Jy/K for ATNF 22 m telescope.
