I provide notes on the NFW Einasto Sersic and other mass profiles which provide good fits to simulated dark matter halos S3. Haloes over the mass range of 10 3 to 10 11 solar masses contribute about equally per logarithmic interval to the luminosity produced by dark matter annihilation which we find.
