I'm working with the theory that Maia is the centre (of the nebula) which gives me three points to play with.
The spike distance represents the distance of other systems with barnacles in them.
There's a fairly close relative match between the distances to Merope and P-Sec JC-U B3-2 and the distances to the closest and furthest spikes.
If that's the case, Pleione would be the 3rd closest spike.
For the theory to hold up the 2nd spike must represent the P-Sec system a bit less than 5ly from Maia and have a barnacle in it.
