Abstract:
We present optical spectroscopy in the range 3300-7400A for a total of
37 planetary nebulae in the LMC and seven in the SMC. Together with
the object from the first paper in the series (1991ApJS...75..407M 1991ApJS...75..407M),
we now have accurate emission-line intensities down to a few percent
of Hβ for 77 nebulae in the Magellanic Clouds. Agreement with
other authors is excellent. Reddening estimates from Balmer line
ratios have been determined, and the line intensities have been
dereddened accordingly. Nebular [O III] electron temperature and,
where measurable, [S II] densities, are derived. [O II] electron
densities are recalculated using appropriate electron temperatures.
The [S II] and [O II] electron densities correlate well, with
ne([O II])>ne([S II]). Zanstra temperatures are in derived for 22
objects possessing detectable stellar continua. These temperatures are
in agreement with photoionization modeling of this sample.
