Description:
We have compiled from the literature 88 emission-line galaxies for
which the published line-ratios give indication of a "transition
spectrum"; selected objects are located north of δ~-20°, are
brighter than B=17 and have z<0.1. We have observed 53 of these
galaxies with the spectrograph CARELEC, attached to the OHP 1.93m
telescope. The observations were carried out during several runs in
May, June and July 1996 and January, March, October and November 1997.
The journal of observations is given in Table 5. The spectra (R∼1800)
were analysed in terms of Gaussians to search for the presence of
multiple line-components, coming from kinematically and spatially
distinct regions - "composite spectra". The results of the fitting
analysis are given in Table 6.

Note (1): When several slices were extracted from the spectrum of a single
object, these were numbered #1, #2, #3 etc.
Note (2): a: an absorption feature was included in the model to fit the blue
spectrum
b: we added an absorption line to fit the red spectrum
t: we corrected the blue spectrum for the stellar contribution by
using a template
q: the red spectrum was corrected by a template.
Note (3): *: the value on the previous column was fixed in the model.
!: profile used to fit the line is Lorentzian, rather than Gaussian.
Note (4): 1: Seyfert 1
2: Seyfert 2
H: H II region
L: LINER
