AFAIK, no EU/PU/PC proponent has provided any material by Lerner to support their case.

Several sets of material by Peratt has been offered, and discussed.

In particular, there's the published results of a simulation by Peratt on how giant inter-galactic currents can give rise to rotation curves of spirals which match those observed for several NGC galaxies. This is complete with several estimates of just the parameters you enquire about in the rest of your post.

Unfortunately, from the published papers alone, the EU/PU/PC case is pretty weak (for example, the surface brightness profiles are out, even ignoring 'zero points', there's no bulge (at all), and a rather nasty inconsistency wrt why these simulations do not include the jets ('beams' in EU-speak) from galactic nuclei (which figure prominently in other Peratt papers). There's more, but I think that'll be enough for now.
