Comparison of light curve (LC) and rotating shutter (RS) velocities. Open circles stand for RS velocities, crosses and triangles for LC velocities. Horizontal axes show height in km, vertical axes velocity in km s^-1. Meteor names in EN format indicate dd, mm, yy. Source of LC velocity consists of Station number (20 – Ondřejov, 02 – Kunžak) and abbreviation describing nature of the record (a – all-sky photographic camera, h – 360 mm long-focus photographic camera, d – digital DSLR camera with all-sky lens).
