\caption{\label{t:etocho-a}Transitions of the \textit{anti}-conformer of ethyl formate observed with the IRAM 30~m telescope toward Sgr~B2(N). The horizontal lines mark discontinuities in the observed frequency coverage. Only the transitions associated with a modeled line stronger than 20~mK are listed.}

 Notes:
 $^a$ Numbering of the observed transitions associated with a modeled line stronger than 20~mK.
 $^b$~Transitions marked with a~$^\star$ are double with a frequency difference less than 0.1~MHz. The quantum numbers of the second one are not shown.
 $^c$~Frequency uncertainty.
 $^d$~Lower energy level in temperature units~($E_{\rm l}/k_{\rm B}$).
 $^e$~Calculated rms noise level in $T_{{\rm mb}}$~scale.
