Query: Redshift Surveys and the Value of Omega   We compare the statistical properties of structures normal and transverse to
the line of sight which appear in observational data from redshift surveys. We
present a statistic which can quantify this effect in a conceptually different
way from standard analyses of distortions of the power-spectrum or correlation
function. From tests with N-body experiments, we argue that this statistic
represents a new, more direct and potentially powerful diagnostic of the
cosmological density parameter Omega.
