To build the mass distribution of exoplanets discovered with the method of measuring the radial velocities, it is necessary to take into consideration the observational selection factors. We propose the detectability-window method to form homogeneous series of exoplanets. In addition, the errors in determining the masses are taken into account. The mass distributions of the transiting planets and the planets discovered with the radial-velocity method are compared in a range of 0.5 to 13 Jupiter masses.
