Description
-----------
 
There are two set of PMTs banks with the generic name Px and PIx, where the 'x'
stands for one or more letters e.g. 'T' or 'HL':-

1)    The PIx family contain the raw data (normally as uncalibrated and 
      in digitized form). Here is a list of all the PIx banks:-

      PIF  ZDAB PMT flags list for all PMT hits.
      PIHL ZDAB PMT charge list for all PMT hits.
      PIHS ZDAB PMT Short-integrator charges for all PMT hits.
      PILX ZDAB PMT Low-gain charges for all PMT hits.
      PIN  ZDAB PMT tube number list for all PMT hits.
      PIT  ZDAB PMT jittered time list for all PMT hits.
      PIT0 ZDAB PMT unjittered time list for all PMT hits.

      Note: For MC data the PIx banks are created in calibrated form but are
      irreversibly converted to uncalibrated form by UCL, which also sets the
      KPIX_DIGITIZED status bit of each bank to signal the change.

      In most cases there is a direct mapping between PIx and the corresponding
      Px although this is NOT true of PIF and PF

       The PIx family, is:-
            Created by   : MCO:  Monte Carlo
            Updated by   : UCL:  Event UnCalibration
            Recreated by : UPK:  Event Unpacker 


2)    The Px family has the data in the processed form.  For MC data this will
      represent "truth".Here is a list of all the Px banks:-

      PF  PMT flags list for all PMT hits.
      PHL PMT charge list for all PMT hits.
      PHS PMT Short-integrator charges for all PMT hits.
      PLX PMT Low-gain charges for all PMT hits.
      PN  PMT tube number list for all PMT hits.
      PT  PMT jittered time list for all PMT hits.
      PT0 PMT unjittered time list for all PMT hits.

       The Px family, is:-
            Created by   : MCO:  Monte Carlo
            Recreated by : CAL:  Event Calibration
       although CAL does not overwrite an existing PF.


Each bank has one word for each PMT hit entry and the banks are synchronised so
that the ith word in each bank refer to the same hit.
