In our earlier work, the median luminosity $L_median(z)$ was calculated, as a function of redshift, of beamed, identical, detectable sources of known redshifts, and compared with the luminosities of nearby GRBs of known redshift. In this paper, we constrain $N(L)dL$ from the observed flux distribution $N(F)dF$ by calculating the expected $N(F)$ from a sample of GRBs with unknown redshift. We compare our theoretical expectations from a physical model with Fermi GBM data and thus constrain the angular emission profile of the GRBs. We find that at wide angles, $N(L)$ is consistent with having a subluminous component, but that it is inconsistent with purely on-axis viewing.
