Additional Stretch OR test

• STR8 tests included many things so that the stretch OR efficiency tests were limited to 15min per point, and only setting exact 3 XY pairs for one tower at a time. This limited the precision on efficiency to +-0.3% even combining all 3 layer combinations. To map out subtle differences between stretch=0,14,31, more data is needed.

• Propose to run 8 towers, with all towers only enabling Layers 0,1,2 combination only for TKR trigger. Cosmic muon data taking driven by CAL LE trigger. Note: TKR hit digis will still be available on all layers in the normal way for track recon.

• Take data at Stretch=0,10,12,14,31 for 45min each. This should give (45/15min)*(8 towers) compared to STR8 3 layer combo of 15 min each. 8 times more data should reach +-0.1% precision.

• Data analysis still very similar to STR8.
