Integrated spectrum in a 1.2′′ aperture centered on the bright continuum source. The spectrum is shown in black with 87 km s^-1 channels, blue lines are individual Gaussian fits, the red line plots the combined fit. The continuum (dashed black line) was measured independently from the same aperture in the line-free continuum spectral windows. The dashed green line shows the integrated [CI] 1−0 profile.
