New page

My first attempt at an efficiency measurement compares wire hits when you require that the first (wire 1) and last (wire 6) wires in a single super layer are hit.

First I looked at which wires were hit when I require that there is a hit on wire 1 and wire 2.

Most of the hits are in row 9 (I was only looking at 16 sense wires)

If I histogram all wire hits requiring a hit in both wire 1, wire 6 and row 9 I see the following

Now I divide by the number of hits seen by both wire 1 and wire 6
