Notes. The full table is available in electronic form at the CDS. Column content: (1–3) upper state rotational quantum numbers 
; (4–6) lower state rotational quantum numbers JKa,Kc; (7) measured line position; (8) least-squares residual in fit I (see text); (9) least-squares residual in fit II (see text); (10) assumed uncertainty; (11) references: TW (this work), B86 (Bogey et al. 1986). Asterisks in Cols. (3) and (6) mark unresolved asymmetry doublets. An empty field in Col. (8) indicates that the line is not considered in fit I.
