UCDlist document update

[Andrea Preite Martinez]

Dear all,

after a first round of comments and suggestions, let me summarize:

1.	I think it will be unwise to re-open the discussion on the already 
standard UCD main document (thus de-classing it back to WD) to ease the 
approval of a second standard, just because we are too lazy to find a 
reasonable spelling for a few words!

2.	Let?s keep changes to a minimum. I found suggestions on the atmol 
and flux/sb words very interesting and worth discussing with more time 
and care. Shortly we will know how to do it ! 
(http://www.ivoa.net/Documents/latest/UCDmaintenance.html)

3.	atmol: I think the simplest solution in this particular case is to 
change the words phys.at.*  into phys.atomic.*

4.	?obtorto collo? (we do it, but we whould have preferred not to do 
it!) we go for phot.flux.density* and phys.energy.density

5.	phys.massToLight can become phys.composition.massLightRatio (indeed 
the ratio has to do with the barionic composition of galaxies or 
clusters of galaxies)

6.	phys.massYield can become phys.composition.yield (also in this case 
the new version is better than the old one - mass just indicated units)

I will wait for a few more days before changing the list of words.

Cheers

Andrea
