Notes. Column one and two indicate the molecular transition and frequency, followed by the half power beam width (HPBW) in arcsec, $\eta_{\rm mb}$ is the main beam efficiency, $T_{\rm sys}$ the system temperature, $\Delta v_{\rm res}$ denotes the velocity resolution, and $\Delta T_{\rm rms}$ the average rms noise temperature per channel on a $T_{\rm mb}$ scale.
