Here is presented some theory of redshift space distortion of some (unspecified
scalar) quantity. In particular a description of the distorted 2-point
function is given and this description applied to relating the redshift
space 2-point statistics to the 1-d statistics along one or more parallel
rays. The application in mind being an understanding of the statistics
of the Lyman-
forest seen in the spectra of nearby QSO's.
Here we only give the results, derviations of these results can be found in an accompanying Mathematica (v3) notebook. Note that the physical theory of the redshift space distortion is not presented here, only a descriptive theory.
