\tablefoot{Numbers in parentheses are 1$\sigma$ uncertainties in units of the last digits. 
For non-detections, the upper limit to the integrated intensity (1$\sigma$) and the observed rms are shown. 
Adopted rest frequencies (MHz) for the $4_{04}{-}3_{03}$, $5_{05}{-}4_{04}$, and $7_{07}{-}6_{06}$ transitions  
are 83~900.572, 104~874.679, and 146~820.687, respectively,
and their corresponding upper energy levels (K) are 10, 15, and 28 \citep{Bru09a}.
For IRAS 16293-2422, line parameters were obtained for both velocity components (see text).}
