| Abstract: | We present the results of theoretical studies of velocity distortions produced by directed motion in a conical source flow on lines with combined Doppler and collision broadening. At 300 K, we find that the velocity effect for an axial velocity of 1×10-5c becomes negligibly small as the line-shape parameter a is increased from 0 to 10. |
