Starting with run 14168 there has been an enhancement of the
Streamer Tube Readout of the WFDs on uVax 1 only. Starting with run
14180 the enhancement is in place throughout MACRO. The TOP face is
now read out for high threshold horizontal streamer triggers. The
current mapping is to read out the top face in modules (half
supermodule) adjacent to the module that has the trigger. Note that
due to microvax-crossing, this is not always possible (see below)
Comments welcome!

Examples:
A Horizontal trigger on Streamer Module 2 should see WFDs
for 1T01-1T17 + 2T01-17.
A Horizontal trigger on Streamer Module 3 should see WFDs
for 1T09-17 + 2T01-17 (+ 3T01-08 after the upgrade on uvax2)
Here is a map showing all combinations of boxes read out:
Scheme for readout of Top Face for Streamer Monopole Events
Notation: Modules 1-11 are the standard streamer horizontal modules
Boxes N-L are top SMN, boxes 1-8
Boxes N-H are top SMN, boxes 9-17

Here is the scheme for Lateral (much simpler) (not yet implemented as
of run 14180)
