Notes.

(a)

Mid-time of the observations recorded as decimal days in May 2004.

(b)

CH3OH transitions marked in boldface indicate blended lines.

(c)

The line frequencies were obtained from the latest online edition of the JPL Molecular Spectroscopy Catalog (Pickett et al. 1998).

(d)

Line intensities and production rates of CO are derived 3-σ upper limits.

(e)

The velocity offsets are computed with respect to the optocenters of the complete components for blended lines.

(f)

Production rates computed for Tkin = 119   K, vexp = 0.90   km s-1, xne = 0.2, and a pointing offset of 2′′.
