Observed [CII] emission of N113. Top: Herschel/PACS [CII] spectra of the target position. We note that the line profiles are predominantly broadened by the spectral resolution of Herschel/PACS, λ/Δλ ~ 1500 (i.e., ~200 km s⁻¹). A flux uncertainty of 10% is assumed for this measurement (see Table Al in Oliveira et al. 2019). Bottom: Herschel continuum-subtracted [CII] integrated intensity map at its original angular resolution of 12″. The two dashed black circles represent the APEX HPBWs of the CF⁺ (2→1) and (3→2) observations, while the Gaussian fitting to the [CII] distribution is indicated by the dashed red ellipse. The 158 µm Herschel HPBW is shown in the lower left.
