Best fit column densities.

Molecule Ntot [cm-2]

Acetone CH3COCH3 1.7 × 1016
Propanal C2H5CHO 2.2 × 1015
Acetaldehyde CH3CHO 7.0 × 1016
Ethylene oxide c-C2H4O 6.1 × 1015

Notes. The results are derived assuming θsource = 0.5″, Tex = 125 K and FWHM = 1.0 km s-1. The column density of propanal was corrected by a factor of 1.489 to take into account the vibrational and conformational contribution at T = 125 K.
