\caption{\label{t:lines-anti-PrCN}Transitions of \textit{anti}-\textit{n}-propyl cyanide, employed in the present fits, their frequencies (MHz), uncertainties Unc. (kHz), and residuals~O$-$C (kHz) between frequencies measured in the laboratory and those calculated from the final spectroscopic parameters. Unresolved asymmetry splitting (two transitions having the same~$K_a$ and the same transition frequency) has been treated as intensity-weighted average of the two lines.}
