Occult Software -- missing predicted asteroid events!
Hi All,
I have recently been generating predictions for occultations by asteroids using the Occult 4.0.8.16 software, and have noticed some oddities.
It seems every time I update the asteroid elements files and re-run predictions, some occultation events disappear and new ones appear.
One example in particular: when I ran on 14 June, I go a prediction that 1107 Lictoria occults TYC 6295-01408-1u on Jul 05 with 49% probability, and the path goes right over Adelaide.
Today I updated the asteroid elements files (Astorb and MPCORB), re-ran predictions, and this event is no longer there!
Is there something wrong with my setup?
Or is this just refinements in the asteroid orbit causing the prediction to no longer occur?
-Ivan
