Kutner, M.L., and K.D. Tucker, 1975: CO, CS, and HCN in a clustering of reflection nebulae in Monoceros. Astrophys. J., 199, 79-85, doi:10.1086/153666.

Carbon monoxide line emission at λ = 2.6 mm has been observed over an area of ∼ 3.5° × 3.5° in LI646, a diffuse dust cloud containing a grouping of reflection nebulae. The H2 mass is estimated from the CO observations to be > 3.2×104M. Five CO emission peaks are observed, each apparently associated with at least one reflection nebula, with the strongest peak at α(1950}= 6h05m20s, δ(1950) = - 6°22'30". Around this position, extended (10' × 10') emission is observed from HCN and CS, suggesting a core with H2 density ≲ 8×104 cm-3. This core appears to be rotating with Ω ∼ 7.4×10-14 s-1. There is also evidence for self-absorption in the CO line in this direction, suggestive of a collapsing cloud.
