Spectral profiles of the CO(1-0) line emission (black) with its Gaussian fit superimposed (red). The lower axis indicates the velocity in km s⁻¹ relative to the line centre at z = 0.327. The dashed horizontal line in black indicates the zero flux level. The line profile has a FWHM of ~400 ± 27 km s⁻¹ and shows a broader and blueshifted wing, which is clearly residual with respect to the Gaussian shape. This could be considered an indication of the presence of an outflow from the CO emitting region, but the spectral resolution is too low (90 km s⁻¹) to draw solid conclusions.
