Top panel: nuclear CO(3–2) spectrum in yellow, extracted in a region. We fit a Gaussian that takes into account the main disk (or “core”) contribution to the CO emission and subtract this from the observed spectrum (residuals in gray). The regions considered in the computation of the molecular outflow properties in the blue and red wings are shown in color. Bottom panel: zoom view of the blue (−400 to −120 km s⁻¹) and red (120 to 300 km s⁻¹) wings. The red wing is integrated only up to +300 km s⁻¹ to avoid the contamination from the H¹³CN emission at ∼400 km s⁻¹.
