Abstract
Constraints are found on the gamma-ray burst luminosity function from an analysis of the combined BATSE/PVO intensity distribution. If burst s originate in an extended Galactic halo, then the intrinsic luminosit y range is narrow, with bursts spanning only a factor of five or less in luminosity. If bursts originate in a simple Friedmann cosmology wit h Omega = 1 and Lambda = 0, then very few luminosity constraints exist .
