Four different cases will be discussed in terms of discriminant analysis
comparing single muons with single pions of known momentum.
All four cases use the same
pad segmentation: 
= 1
and 
=
2.813
, 2.813
, 5.625
, 5.625
,
5.625
, 5.625
. In addition, all
four cases use the same discriminant variables: 1, 2, 5, and 9.
These numbers represent the following variables:
1: Last Plane Hit
2: Total Hits
5: Rho Max
9: Front to Back Ratio.
We use PISA/PISORP and the muon arm group's MUN code developed at GSU, ORNL, and VU for these studies. The cases differ in their 'per plane efficiencies.'
Case #1 has a "per plane efficiency'' of 98% on each of the 6 planes.
Case #2 has a "per plane efficiency'' of 98% on the first 3 planes and 90% on the last 3 planes.
Case #3 has a "per plane efficiency'' of 98% on the first plane and 90% on the last 5 planes.
Finally, one more issue is addressed. This issue is that of the importance of the last plane. For this purpose, Case #4 is to be compared to Case #2.
Case #4 has a "per plane efficiency'' of 98% on the first 3 planes, 90% on the next 2 planes, and only 1% on the last plane.
