### Step 1 Analysis:The Story So Far

V. Blackmore

• Previously:

• Oddities in the x-distribution at TOF0 (lumps and bumps)  Problem fixed.

• Was also something odd happening w.r.t. dispersion in the horizontal and vertical planes  Problem persists (?)

• What do we mean by ‘dispersion’?  Also looked at the relationship between x at TOF0 and x at TOF1. Again, ‘the plot thickens.’

• Very little interference in these plots from reconstruction technique. Just the positions as measured by the TOFs!
