Abstract: 

We present a new method for the calculation of parameters of low-velocity components of bipolar outflows in molecular clouds. The method takes into consideration all possible manifestations of a bipolar outflow in line spectra: asymmetry of line profiles, existence of line wings and systematic shift of the profile along the outflow axis. Our method is adapted for the calculation of parameters of weak bipolar outflows as well as of the outflows whose spectra are characterized by low signal-noise ratio. Using the method, the parameters of bipolar outflows observed in the line of 13СО (J = 1-0) molecule in the G122.0-7.1 source are calculated.
