The problem to retrieve the true mass distribution from Radial velocity (RV) measured data. The RV measurements produce projective mass which is the true mass times sin(i), where i means the angle between the line to observer and the exoplanet orbit plane. Several algorithms have been discussed here, because the inverse Abel integral transformation fails in the non-regularized, non-smooth raw data.e the whole RV exoplanetary database represents a non-regular data, which cannot be used for the retrieving the true mass distribution as row data. We have elaborated the algorithm to filter the exoplanets which are regular and less contaminated by observing selection.
