get_names(

)-> ‘InventoryNames’
Return the names this inventory could contribute to a patch.
These are the names Patch.enrich can be asked for and selection can query, split by where each lands: attrs for the observing-system facts, which are scalar per patch, and coords for the names taking a value per channel. attrs is the same for every inventory, since the models decide it; coords depends on what this inventory holds.
Contributing a name is not promising a value for it: a name is listed when some acquisition or optical path could define it, and one which none does simply resolves to nothing.
