Constraints on the <strong>Central</strong> Engine<br />
• Cosmological ➙ Huge Energies (~10 49 -10 52 ergs, collimated)<br />
• Energy / Millisecond Variability ➙ Black Hole or Neutron Star<br />
• <strong>Gamma</strong>-<strong>Ray</strong> Spectrum ➙ Ultra-Relativistic (Γ ~ 100-1000, M jet < 10 -5 M )<br />
• Late Flaring (t flare /t GRB ~ 10 2 -10 4 ) ➙ Engine Active Long after GRB<br />
