Positions of the radiants of predicted (various black symbols) and real meteors separated from the C (blue asterisks), S (green crosses), E (orange empty squares), R (violet triangles), and F (red plus-symbols) databases. Panels a and b: radiants of showers #726 and #628, respectively, and the predicted filaments corresponding to these showers are shown. The apex-centered ecliptical coordinate frame is used.
