Okay. We can't ask for more than that.

I would imagine FITS would be best - in most cases we will have a spectral
header that can be fully Paper III compliant (note that in some cases I
will be making GAIA display a time series so headers are a bit of a
problem there - a table of time + value would be better then).

Any chance that you can ping the plastic people to find out what VO-Spec
