Notes.

^(a)

Fluxes obtained from the Gaussian fitting to the line profiles, and multiplied by a temperature-to-flux conversion factor of 5.0 Jy/K that is appropriate for the 30 m telescope at all observed frequencies.

^(b)

All velocities are heliocentric.

^(c)

Resolution-corrected line width.

^(d)

All limits are computed at 3σ levels.

^(e)

A standard CO-to-H₂ Galactic value of 4.6 M_⊙ (K km s^-1 pc²)^-1 was used for the mass computation. The 3σ limits were computed for a width of 47 km s^-1. This is close to the median ¹²CO(1 − 0) width for all regions but the plume and NGC 4438.
