Started looking at 3 wires, straw 17 (central) which is one of the better resolution straws, and then straws 7 and 5 which are worse.

Wiggled wire positions in a 9x9 grid for wires in the order 17, 7, 5, starting with box width 160um (9 boxes in the grid) and halving box size for each step, down to 5um. Minimized fitted gaussian width/height. 1e5 cosmic events total. Detector at 45 degrees.
