Dear all,
I received from the IVOA Exec a request to modify all UCD1+ words that do not conform to what is said in the standard UCD document, i.e.:
UCD1+ words at the same level in the hierarchy cannot be a starting substring of another
that is, we cannot have phot.flux and phot.fluxDens
As you know, the document at
http://www.ivoa.net/Documents/latest/UCDlist.html
is in the PR status, and will be moved to IVOA Recommendation after an
appropriate action on the words concerned.
The rule mentioned above is violated for the following ucd1+ words:
E | phot.fluxDens | Flux density (per wl/freq/energy interval) E | phot.fluxDens.sb | Flux density surface brightness Q | phys.atmol | Atomic and molecular physics (sharedproperties)
Q | phys.atmol.branchingRatio | Branching ratio Q | phys.atmol.coll | Related to collisions Q | phys.atmol.configuration | Configuration Q | phys.atmol.crossSection | Atomic / molecular cross-section Q | phys.atmol.element | Element Q | phys.atmol.excitation | Atomic molecular excitation parameter Q | phys.atmol.final | Quantity refers to atomic/molecular final/ground state, level, ecc. Q | phys.atmol.initial | Quantity refers to atomic/molecular initial state, level, ecc. Q | phys.atmol.ion | Ion S | phys.atmol.ionization | Related to ionization S | phys.atmol.level | Atomic level Q | phys.atmol.lifetime | Lifetime of a level Q | phys.atmol.lineShift | Line shifting coefficient Q | phys.atmol.parity | Parity Q | phys.atmol.sweight | Statistical weight S | phys.atmol.trans | Transition between states Q | phys.energyDensity | Energy-density Q | phys.massToLight | Mass to light ratio Q | phys.massYield | Mass yield
because of the already existing words
phot.flux phys.at phys.energy phys.mass
In order to reach a rapid convergence on the reformulation of these words, I?m suggesting a possible solution for each of them in the list that follows:
Present Suggested new
E | phot.fluxDens | phot.flux.fluxDens or: phot.flux.density
E | phot.fluxDens.sb | phot.flux.fluxDens.sb or:
phot.flux.density.sb
Q | phys.atmol | suppress
Q | phys.atmol.branchingRatio | phys.branchingRatio
Q | phys.atmol.coll | phys.collision
Q | phys.atmol.configuration | phys.state.configuration
Q | phys.atmol.crossSection | phys.crossSection
Q | phys.atmol.element | phys.element
Q | phys.atmol.excitation | phys.excitation
Q | phys.atmol.final | phys.state.final
Q | phys.atmol.initial | phys.state.initial
Q | phys.atmol.ion | phys.element.ion S |
phys.atmol.ionization | phys.ionization
S | phys.atmol.level | phys.level
Q | phys.atmol.lifetime | phys.level.lifetime
Q | phys.atmol.lineShift | phys.lineShift
Q | phys.atmol.parity | phys.state.parity
Q | phys.atmol.sweight | phys.state.sweight
S | phys.atmol.trans | phys.state.trans Q |
phys.energyDensity | phys.energy.density
Q | phys.massToLight | phys.mass.light
Q | phys.massYield | phys.mass.yield
The other possibility for the phys.atmol.xxx group is to suppress the word phys.at
Please let me know your opinion and/or your suggestions.
