  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 (xa, ya) (xc, yc) B C (xb, yb)

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

  5. Calculating intersection point (2) • c2 = S (width(x,y)/swid )2

  6. Theta square distribution (2) • Cross line : On data • Red line : Off data

  7. Upper limit • Use calculating method No.2 • Line is Crab integral flax • F(E>640GeV) = 2.2 x 10-12 photon/cm2/sec( ~5% Crab flux)
