MES, EMMI, and synthetic P-V arrays. The arrays on the left column (labelled AAT) are those for a long-slit applied to the major axis of the nebula using MES, whereas the right column (NTT) shows the arrays for a long-slit placed across the minor axis using EMMI (see Fig. 12b for these slit positions). The P-V arrays on the top panel and those on the central panel are the same, except using different stretches of the intensity scale. Shown at the bottom (MODEL) panel are the corresponding synthetic P-V arrays, which were generated using the SHAPE model.
