Hi, Frank:
The FTPC mult is not in the event summary. Xin is modifiying the
MuDSTMaker to reproduce TOFr trigger dataset into miniDST.
Thanks!

Was this reference multiplicity available during the latest dAu
production? If so, where would it have been stored? If it was somewhere
in a private FTPC collection (or online derived from it) then obviously
it wasn't available, however if it was stored somewhere in, say, the
event summary then we do have it ... somehow I have the impressionthat
the whole issue of FTPC's ref mult came up /after/ the dAu production,
right?
Of course, having the TOF information in the MuDST is our next step.
But, that will never be the full TOF data set: it can only be the
matched cells and slats. (which implies that we need to introduce TOFp
and TOFr match makers and some point before the next production of
MuDSTs start)
cheers,
frank
