Our test with mock samples shows furthermore that one can discriminate among such models already with currently available observational samples ( if the measurement error of the redshift is negligible ) which have a typical error of 80kms - 1. the error will be reduced by a factor of 2 if the samples are increased four times. we also show that an errroneous assumption about the geometry of the universe and different infall models only slightly change the results
