Notes. (a) Δα and Δδ offsets relative to the position of the nucleus α,δ (J2000): 10h39m52s.5, + 20°50'49''. (b) At 10.9 km s-1 velocity resolution. (c) 
with 
. For the non-detections, we take 
and assume ΔV = 100 km s-1. (d) Fitted line widths, not deconvolved by the spectral response. (e) Fitted, relative to the systemic velocity 13 830 km s-1. (f) Σmol = 2mpN(H2). Values for X = 2.0 × 1020 cm-2 K km s-1 (cf. Sect. 3.4). (g) From Fig. 3 of Pickering et al. (1997). (h) 
with Z = 0.45, X = 2.8 × 1020 cm-2 K km s-1 and i = 38°. Values in brackets assume Σmol ≪ ΣHI. (i) Using Σcrit from Fig. 10 of Pickering et al. (1997), re-scaled for σgas = 13 km s-1.
