Analysis report of SN1006 D.Nishida( Kyoto-Univ.) JPS meeting Autumn 2005 Osaka
Cut parameters -30 ns < TDC start < 30 ns 5 p.e x T5a Distance from camera center < 1.6 deg Likelihood ratio > 0.7
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)
Theta square distribution (1) cross line: On data red line: Off data Effective time sec(17h)
width(x,y)/ wid Calculating intersection point (2)
Theta square distribution (2) Cross line : On data Red line : Off data
Upper limit Use calculating method No.2 Line is Crab integral flax F(E>640GeV) = 2.2 x photon/cm 2 /sec( ~5% Crab flux)
