Plot of the rate for model “delay power”, which yields the minimum rate (see Appendix B), as a function of the GRB opening angle θ and the parameter η. The other parameters are kept constant as they are more reliable. The color show the rate in units of Myr-1 Mpc-3, and the black lines delineate the areas excluded by GW upper limits in the case of NS-NS and NS-BH binaries (LIGO Scientific Collaboration and Virgo Collaboration 2010b); the lower left areas are excluded.
