The Dark Matter Annihilation Signal from Dwarf Galaxies and Subhalos

Table 2

Estimated luminosities and fluxes for the 18 dSph from Table 1. ℒ_tot is the total luminosity and ℒ_0.3 the luminosity from within the central 0.3 kpc. ℱ_tot=ℒ_tot/4𝜋𝐷² is the total flux and ℱ_𝑐 the flux from a central region subtending 0.15^∘ (about the angular resolution of Fermi above 3 GeV). The first number is the median over all subhalos matching the dSph distance and 𝑀_0.3, the numbers in parentheses are the 16th and 84th percentiles. The table is ordered by decreasing ℱ_tot.
