[CI](1−0), [CI](2−1), [NII], and [CII] noise distributions. For each panel, the spatial noise distribution as well as the histogram of the noise distribution are shown. The noise distribution spatial maps are centred at the α(J2000) = 17^h45′39.9′′, δ(J2000) = −29°00′28.1′′ position. From the spatial maps, the noise is higher at the edges of the maps, as expected given the small number of spectra at the borders with which to calculate the resampled spectrum. From the histograms, a Gaussian fit (solid curve) shows the typical noise of each map C_fit (Gauss centre shown as a vertical dashed line) and the standard deviation of the distributions σ_fit.
