Gaussian fit of the [Ne V] 14.32 μm and [Cl II] 14.37 μm fine-structure emission lines at three different pixels of the IRS/SH map. The error bars indicate the uncertainties of the spectral data. The filled circles indicates the pivots used for the cubic spline interpolation of the baseline. The top panel shows less than 3σ detection for [Ne V] but a clear detection of the [Cl II] line. The spectrum of the middle panel shows clear detections of both lines. The bottom panel shows  <3σ detection for [Ne V], in spite of the low uncertainties in the data points.
