These estimators are tested on mock samples of {\\it Cosmicflows-3} dataset \\citep{Tully:2016aa} , derived from a numerical cosmological simulation, and also on a number of constrained realizations of this dataset. Observational measurements errors and cosmic variance are taken into consideration in the study.
