The reason is that nobody else talks spectra! PLASTIC capabilities
in VO-Spec seem pretty flaky. You should be able to send a spectrum
to TOPCAT as a VOTable if you want.
In fact the situation of PLASTIC messages regarding spectra is not
very good. Currently AstroScope normally sends spectra around as
FITS tables, calling them FITS images. This is largely a consequence
of (IMHO) inadequacies in the SSAP standard, though imprecision of
currently available PLASTIC messages doesn't help. Basically spectra
over PLASTIC is a bit of a mess at the moment, I'd better try to
sort this out, though the required discussions on the various IVOA
lists etc don't fill me with enthusiasm. Anyway, once the standards
are sorted out properly, SPLAT will need some tweaks to implement
them properly, but the machinery's all in place, so the additional
work should be pretty minor. Since the current SPLAT's not in keoe or
any very official release, I guess this flakiness doesn't matter too
much. I'm providing a JNLP link which I'll put on the PLASTIC
web site (plastic.sourceforge.net), but this is mainly going to be
for demos, testing, proof of concept etc at this stage (I assume
you've got no objection).
