New way of constructing the complete sample of radiosources with known redshifts

A comprehensive sample of radiosources with known redshifts is constructed. Optical and radio selection limits are replaced by their linear combination. The sample, consisting of both quasars and galaxies and numbering 91 objects, is shown to be nearly complete. The luminosity function of radiosources is determined over the range of radio luminosity at frequency 1400 MHz, 19 < logP 1400 < 27, where P1400 is in W Hz-1 ster -1, based on the constructed sample.
