We compare the field-field g(1)(\tau), intensity-field g(3/2)(\tau), andintensity-intensity g(2)(\tau) correlation functions for models that are ofrelevance in astrophysics. We obtain expressions for the general case of achaotic radiation, where the amplitude is Rician based on a model with anensemble of harmonic oscillators in Brownian motion. We obtain the signal tonoise ratios for two methods of measurement. The intensity-field correlationfunction signal to noise ratio scales with the first power of |g(1)(\tau)|.This is in contrast with the well-established result of g(2)(\tau) which goesas the square of |g(1)(\tau)|.

A comparison of g(1)(\tau), g(3/2)(\tau), and g(2)(\tau), for radiation from harmonic oscillators in Brownian motion with coherent background
