Hi Bill,

There will be some uncertainty in the result from Analyser if its profile was created from a small number of reference stars.

Analyser sometimes categorises a meteor as a sporadic (or other shower membership), giving an unexpected result. Two reasons for this can be the meteor’s angular velocity and its distance from the radiants stored in its internal catalogue. The meteor’s estimated velocity is an important factor and if this falls outside the expected ranges (for each known shower) it can fail the shower membership tests and be categorised as a sporadic.

Have a look in the UFO Analyser Uty tab and tick the ‘analyzelog’ box. This creates a txt file when analysing a meteor clip. The file contains details about the reference stars, the meteor’s angular velocity and how well it matches against currently active slowers.

Clear skies,
