Dear All,

Genna wanted that we install 4 layers. We disagreed and
finally installed only 3 layers.

This is correct. The first layer is just before epc1, the
second just before epc2 (which means that the exit of epc1
is "free" of mesh until it reach the next chamber). The gap,
which originaly contains chamber #4 is empty. Epc2 is
covered before and after with mesh. Thus the third one is
just after epc2.

Francoise
