1. Analysis report of SN1006 D.Nishida( Kyoto-Univ.) JPS meeting Autumn 2005 Osaka

2. Cut parameters -30 ns < TDC start < 30 ns 5 p.e x T5a Distance from camera center < 1.6 deg Likelihood ratio > 0.7

3. Calculating intersection point (1) x’ = (xa*sinA + xb*sinB + xc*sinC)/(sinA+sinB+sinC) y’ = (ya*sinA + yb*sinB + yc*sinC)/(sinA+sinB+sinC) A B C (xa, ya) (xb, yb) (xc, yc)

4. Theta square distribution (1) cross line: On data red line: Off data Effective time  61089 sec(17h)
