Hello Cees,

I'm member of BRAMON - Brazilian Meteor Observation Network and I have 3
cameras to record meteors that record some orbiting objects too. The
recorded videos are processed in UFO Analyser software used for analyse
meteors (not UFOs). The camera position is fixed, so we create a astrometry
mask in a starry night and used it for future records with only little
corrections.

After processing, UFO Anlyser returns for each frame the coordinates of
moving object position. So, I created a excel sheet to convert output of
Analyser into IOD format (and fixed a bug in it just now). Above the
corrected reports.

Thank You!
