Notes. Fν includes 10% calibration uncertainty. FWHM uncertainty is determined as the maximum between the uncertainty in the fitted Gaussian and the channel width. Column densities N were calculated assuming optically thin emission from a gas in LTE at 124 K. Furthermore, the column densities assume that the emission fills the beam. Toward L483, (a) denotes the weaker blueshifted component and (b)the brighter redshifted component.
