Description
-----------
 
    One bank generated for each event by each fitter.  Each type of fitter
produces its own type of FTx bank, for example, the quad fitter produces an
FTQ bank.  The first part of the summary bank for all fitters is the same, and
it is this common part that is described here.  If a fitter produces further
words then an entry will appear in this list:-
 
FTC The Stopping muon fitter 
FTE The elastic fitter
FTG The grid fitter
FTI Muon "Impact parameter" fitter
FTK Energy fitter
FTM The muon fitter
FTP The path fitter
FTQ The quad fitter
FTR Through-going Muon Fitter
FTT The time fitter
FTU The (QPDF) fitter
FTY The Charge only Muon "Impact Parameter" fitter
FTZ The Time only Muon "Impact Parameter" fitter

Structural Links
----------------
 
 -1  -KFTX_FTXV  FTxV   Link to first fit vertex.
 -2  -KFTX_FTXA  FTXA   Link to fit analysis bank.
 
 
Status Bits
-----------
 
Note: Any status bit parameters are defined to work with bit functions such as
      IAND and BTEST.
 
 
Data Words
----------
 
    Data types: B(bit), I, F, D(double), H(hollerith 4 char)
 
 +1  I KFTX_METHOD     Fitter method: e.g. KFT_TIME.
                       See bank_ft.inc for a complete list.
 +2  I KFTX_RETC       Return code.
                       See processor return codes in su_com.inc e.g. KSU_OK.
 
Only the above words are common to all fitters. However, for those fitters for
which the following words are relevant, it is recommended that they follow this
format:-
 
 +3  I KFTX_PMT_AVAIL  No. of PMT hits available.
 +4  I KFTX_PMT_USED   No. of PMT hits used.
 +5  I KFTX_EARLY      No. of early PMT hits rejected.
 +6  I KFTX_LATE       No. of late PMT hits rejected.
 +7  I KFTX_ITER       No. of fit iterations.
 +8  F KFTX_PROB       Fit probability.
