The spectra were deredshifted assuming *z* = 0.0434
(Fig. a and b) and
analysed in terms of Gaussian components as described above. We discovered
first that the core of the lines could not be fitted by a single set of
narrow Gaussian profiles. To get a satisfactory fit, two sets of Gaussian
components are needed: the first, unresolved (and subsequently taken as the
origin of the velocity scales) has 6583/H = 0.55 and 5007/H = 1.27 and
corresponds to a Hii region (Fig. ); the second is resolved
(FWHM 350 kms^{-1},
corrected for the instrumental broadening), blueshifted by 95
kms^{-1} with respect to the narrower components and has line intensity ratios
typical of a Seyfert 2 (6583/H = 0.84, 5007/H = 10.2).
