Further follow-up spectroscopy was made during nights May 30 - June 4, 1995,
using the Boller & Chivens spectrograph attached to the Cassegrain focus
of the Calar Alto 2.2m telescope. A 300''2'' long slit was used.
The spectra were recorded on a 1024
1024 pixel Tektronix CCD operated
in a 2
1 binned mode (binning only along the slit direction),
resulting in a spectral resolution of 9 Å and
a wavelength coverage
3700-8100 Å.
The exposure times varied between 2.5 and 15 minutes depending on the galaxy
brightness. The observations were complemented by standard star flux
measurements, lamp exposures for wavelength calibration, dome flats, bias and
dark frames. The seeing was mostly about 1'', rising at times up to 2''.
The observations during the second and the last night were made under
non-photometric conditions. The flux calibration for the dozen objects
observed during the second half of the last night is especially uncertain.
