Quick question - gold for lost wonders

[ArcaneSeraph]

I'm wondering if there's value in XML or a way in lua to change the amount of gold you get for production put in lost wonders.

I'm working on a mod that rebalances quite a few things and it makes sense to increase this amount but can't seem to find this value (or what it would be called). If anyone has stumbled across a way, a point in the right direction would be much appreciated.
