West vs East Purity SouthNorth LE + UELW + UWLE + UELW + UW # of Triggers80k1M90k1.3M Reconstructed Roads (nroads/event<50) 16k Purity20 %1.6 %17 %1.2 % Since number of reconstructed roads are same between East and West, the purity is better in East side. Contradictory to our expectation, west is not likely be efficient in purity. West is rather suffered from junk triggers.

5. Number of Roads Only 10 ~ 20% of total roads belong to number of roads<50. However, the nroads<50 distribution looks good. South North

6. RadioGraph SouthNorth East / West Asymmetry in the trigger is not seen and roads are uniformly distributed. Hot regions are panel overlapping region. Perhaps be expected?

South could be off by 1 BCLK or so.
