Analysis of Draco with EGRET Larry Wai September 9, 2002
Dark Matter Search at Draco • See C.Tyler, Phys.Rev.D 66, 023509 (2002) • Location of Draco is (l,b)=(86.370,34.710) • Nearest 3EG source is 410 distant • Angle cut keeps at least 67% of photons for given energy band: q < 5.850(E/100MeV)-0.534 • Use 60 < q < 100 annulus around Draco for background estimates • Use photon lists (qvp files) and energy/angle dependent “exposure” maps (exp files)
Viewing Periods with Draco at least 100 from edge of exposure map
