Err.. so if I find an ELW, that goes straight into the Codex with it's location for everyone to see, before I get to sell the data at a station???
If so, that seems really contradictory - somehow a discovery is magically broadcast into a universal Codex immediately, but we don't get the credits until that discovery is sold at a UCarto site??
It only goes into the Codex for everyone else to see if it happens to be the very first one of that particular type discovered by any commander in the entire region. But, yes, if you are the very first to discover an ELW anywhere in the region, it is broadcast immediately. If you are not the first, then nobody else sees it.
