This paper analyses the effects of random noise in determining errors and confidence levels for galaxy redshifts obtained by cross-correlation techniques. The main finding is that confidence levels have previously been overestimated, and errors inaccurately calculated in certain applications. New formulae are presented.

Particles with energies below the mean energy E 0 in relativistic shocked plasmas should assume an equilibrium energy distribution. This leads to a synchrotron spectrum F ν ∝ ν 1/3 up to approximately the critical frequency ν 0 of an electron with the energy E 0. Application to GRBs implies that a burst with 10 −5 erg/cm 2 s of soft gamma-rays and hν 0 = 300 KeV should be about 18th magnitude i...
