I'm not sure if you're talking about processing this data with cavern,
or trying to load it into aven, but either way there isn't a fixed limit
on the number of legs or stations that can be handled.

What sort of grid size are you working with?  And where exactly are you
apparently hitting a limit?

The only real limit is memory, but modern machines have so much memory
that I'd be surprised if you were hitting that limit.

There aren't any fixed size arrays to increase the size of.
