It looks as a problem of lox generation. But it should be a bug.
Check attached picture, mostly all splay shots from station 4-10 are going upside. But it has not changed I added to stations dummy „down“ shot

Hi guys,
Here is the .th and .th2 file from a survey of a large chamber. What I don’t understand is why the line survey is outside below the chamber. Any advice on how to fix that ?
Thanks,
Phil
