Integrated intensity maps of IC 1396D derived using different methods and thresholds at 16″ resolution. The upper three panels are from the 3D dendrogram method, with thresholds of 1σ, 2σ, and 3σ from left to right. The middle three panels are from the masked moment method, also with the threshold of 1σ, 2σ, and 3σ from left to right. The bottom panel is the direct integration of the spectra with the velocity range from –12 km s^–1 to +10 km s^–1. See the main text for details of the different methods. Black crosses with numbers mark positions where the masks along the spectral axis are shown in Fig. B.3.
