This directory contains nodes useful for working with Farfalla and Dash.
The Nodes will eventually be incorporated into macrofar, so check with 
Chris Walter for the latest and standard versions of these in the future.

Stop Master Node
================
Version 2 is the current version.  The Stop Master Trigger and Tohm
Face register bits were added to version 1.  Some of the bits were
swapped, and since I already had a lot of data on disk at Gran Sasso I
made a version 2 that corrected this (but kept version 1 to look at
the data).  The triggers and hits are now part of one big array.

   dreamMakeStopNodes.cc    Node creation routine for use with duser.cc
   stopTest.cc              A simple dash module to read Stop Master data
   
CSPAM Node ***
==============
Version 2 is current.  The CSPAM decoding is now correct.  Previously
the roles of High Energy/ Low Enrgy and lower patch/upper patch were
reversed, causing some scrambled data indeed.  There are some fixes to
deal with upside-down cables in the CSPAM in dreamMakeCspamNode.cc that
are currently commented out.  Starting with Version 2 there are
independent trigger registers for CSPAM/HIP/FMT hits.  The bit order
for these registers is as follows:

bit 1 SM12 Event, MVAX1 (first bit on left)
bit 2 SM23 Event, MVAX1
bit 3 SM23 Event, MVAX2
bit 4 SM34 Event, MVAX2
bit 5 SM45 Event, MVAX2
bit 6 SM45 Event, MVAX3
bit 7 SM56 Event, MVAX3

These bits are decoded from the Scintillator Pattern Register (Erik's
Module).  Note that bits 2&3 and bits5&6 have very different meanings
(even though they should always be identical given an event (or pair
of events separated by more than 10usec!!), provided something else
didn't happen to cause a VETO on one of the microvaxes.  The WFD
Readout for HIP/FMT will only occur locally on one microvax.

WFD Analysis Tools
==================

   multiplot.cc             Multiple WFD HIGZ plotting routine. 
                            use TALK HELP for instructions
                            Requires the tankMap class

   wfdch.cc                 Checks that waveforms exist for all hits
                            Requires the compList class

Classes
=======

   compList.h               Comparison List Class
                            (in development)
                            Holds lists of integers and performs useful
                            comparisons between lists

   tankMap.h                Tank Mapping class
                            Initialize this object to be one of several
                            scintillator trigger box names, including:

                            Wfd Chan, bit
                            ErpBox, tank end
                            SM, tohm word, tohm bit
                            SM, lip word, lip bit
                            Tank Name string
                            (soon CSPAM/FMT/HIPT will be added)

                            Once it is initialized, member functions
                            will return valus for other corresponding 
                            numbering schemes.

                            The point of this is to never have to write
                            a mapping subroutine again.  I admit that I
                            overuse it.  Possibly it's functionality
                            should be incorporated into each node somehow.
