Reconstructing PSCz with a Generalized PIZA

We present a generalized version of the Path Interchange Zel dovich nApproximation (PIZA; Croft and Gaztanaga 1997; hereafter CG97), which may be nused to reconstruct density and velocity fields from realistic galaxy redshift nsurveys. The original PIZA does not include the possibility of using galaxies nin redshift space with a selection function. We map galaxy posi..
