Hi Ian, Claus and others,
We've looked very briefly and qualitatively at vertex correlations
here in Oslo too, and we see nice correlations between BB and ZDC and
between BB / ZDC and track intersections with the beam plane (much like
Claus' plots) - there's only the question of an offset. From run 3969,
I very roughly determined "by hand":
bbpos = bbpos(raw) - 9 cm (approximately)
zdcpos = zdcpos(raw) - 42 cm (very inaccurate)
where the "raw" values are the ones delivered by BrBbRdoModule and
BrZdcRdoModule.

We're working on translating the BrTPMClusterVertexModule and
BrTPMTrackVertexModule to the Brat2 TPC class standard - our eminent
vertex expert Bjørn is unable to work full time on this right now,
but Truls, Bjørn and I will try to come up with something within the
next 1 - 2 weeks.
Best wishes,
Trine
