Radiant positions of the particles modeled using a cloned orbit of the comet. The positions of radiants are shown in the same way as those in Fig. 1a. However, the initial orbit to model the stream was the cloned orbit No. 4 and P-R drag influenced the motion of modeled particles in this case. In plot a), the stream was modeled in time 10 kyr before the present and parameter β = 0.002. In plot b), the stream was modeled in time 20 kyr before the present and β = 0.009.
