It would begin somewhere and spread out as a wave, though there might be a few leaders and laggards. This data of Arp's is hard to explain any other way. Sorry, I do not have a reference for that.
Nereid: If you don't have a reference for it, what merit should this have, in any scientific investigation?
For example, I could claim that "[t]his data of Arp's" was all made up, late one evening after a too many pints at the local pub. Without a reference, how can anyone reading this decide, objectively, whose story is right?

Yes, I accept that references are needed. Unfortunately I did not always keep records of references in my early work and even when I did, I made about 40 notebooks full of stuff, so I cannot always find them. These things are still useful as notes, because someone who sees them may see an explanation of make a connection and go search it out. I did a quick web search without success.
