after my discussion with Bruce this morning, I have come to the following understanding.
  1. I have put the derivation of the unit conversion into the pdf that I uploaded to the forum.
  2. The POCA to the reference point indeed must be calculated in 2D, otherwise the definitions don't make sense, especially the calculation of d0 in terms of phi0 depends on this. The HelixSwimmer in org.lcsim seems to do the right thing, but I have not yet explicitly tested that.

Edit: Due to a lapsus, I was originally under the impression that the conversion should be the reciprocal of its true value. I have fixed the attachment.
