Detailed Description

A field that is unique for each TPC micromega pad.

sss x f ppppp bbbbbbbbbbb
s(3) -- The tpc (0 to 2)
x(1) -- The half of the drift volume (0=-x, 1=+x)
f(1) -- The pad flag.  This is 1 if the id is for a pad.
p(5) -- The micro mega (0 to 16)
b(11) -- The pad number (0 to 1727)
