Re: Units of NTv2 accuracy/error channels ?

I've initiated in PROJ wiki a page with the NTv2 products currently in 
the proj-datumgrid repository and which have accuracy channels with 
significant values:

https://github.com/OSGeo/PROJ/wiki/Units-of-NTv2-accuracy-samples-%3F

Please help filling it if you're from, or have contacts with, LGL, LINZ, 
Ordnance survey, IGN Belgium, Swisstopo, DGTerritorio or ICSM....

Even

PS: For clarity, I've omitted all the NRCan NTv2 grids other than ntv2_0.gsb, 
as I assume that NRCan consistently uses metres, and similarly just kept one 
product for Swisstopo and DGTerritorio as they seem to be consistent too.
