Re: SED serialization

Paolo,

 Thanks for your posting of Feb 2; sorry for the delay in responding. Your questions are good ones but basically the answer is that they are all enhancements post version 1.0. I know that's not the answer you want!

A new version of the doc is on my web site at

 http://hea-www.harvard.edu/~jcm/vo/docs/spec102/specrc2.pdf  http://hea-www.harvard.edu/~jcm/vo/docs/spec102/specrc2.html

I'll send it to the VO doc coordinator if it survives a couple days without anyone spotting horrible errors in it.

• About the FITS serialization. You are right about the binary table implementation and that a SED could be written with multiple rows; although at ADASS we agreed to postpone the implementation of the multiple-row SED support for now. The typesetting of the data in the section 9.4 example is perhaps misleading; it depends how your FITS application would represent the binary data in the table - better to concentrate on the TTYPE/TFORM keys to see what is intended.
• Magnitudes. Again, at ADASS we agreed to postpone the implementation of a full photometric model with transmission curves to a later date; it will use the spectrum model but add the zero point and the transmission curve.
• Hence, we're postponing work on the Spectral Associations until after the current doc is approved, hopefully very soon. The old draft of the doc is http://hea-www.harvard.edu/~jcm/vo/docs/spec96/sed96.pdf - but I know that Doug Tody wants to take a different approach.
• Schema errors. Yep, we had already caught these and they are fixed in the new version.
