Positions of the slits used for high-resolution spectroscopy superimposed on a gray scale and contours reproduction of the [N II] image of Me 2-1. The slits are labeled by their PA (see the text and Table 2 for such details as, e.g., slit width). A long-slit at PA −25° was also used for the intermediate-resolution spectra (see Sect. 2.3). The scale and orientation of the image are indicated. The dashed circle represents the mean seeing in the long-slit spectra (see Table 2).
