---+ VOUnits next steps There are no current plans to develop the VOUnits specification. However this page collects a few minor errata and suggestions for future work, which can be addressed if such plans do eventually emerge. Below is a note of minor fixes already applied (by Norman) * The list of 'deprecated by FITS' terms in Table 2 is slightly ambiguous. I've adjusted the text in the repository version of the standard, to clarify that these 'deprecations' derive from Table 4 in the FITS spec (which actually says they're deprecated by the IAU but doesn't take a position on the matter itself). * The besselian and tropical years are _not_ mentioned in that list of FITS-deprecated units -- they appeared by acclaim in the on-list discussions, and so ended up in the VOUnits list. I've removed them from the FITS column in the Unity library (which is what generates the document's Table 2); they're still recognised-but-deprecated in VOUnits. * The units 'angstrom' and 'ohm' (as unit names) are correctly spelled with a lowercase initial letter, but in both cases their usual unit _symbol_ is a non-ASCII character, so that their all-ASCII version here must be a word. Following the lead of the FITS and CDS standards, and of SI unit-symbols derived from surnames, and disagreeing with the OGIP standard, we have preferred the initial-capital symbol in VOUnits (thus `Angstrom' as the unit symbol, rather than `angstrom'). See [[https://code.google.com/p/volute/source/detail?r=2754][volute commit]] for the document, and [[https://bitbucket.org/nxg/unity/commits/b45b533ada39f44e04540ef6372eab67a6827f61][unity commit]] for the library. -- IVOA.NormanGray - 2014-10-27 <br/> <!-- * Set ALLOWTOPICRENAME = IVOA.TWikiAdminGroup -->
