shape of uniform2 distribution

Author: John Lattanzio
Posted: May 2, 2017 at 8:02PM

Am I doing something wrong? I get zero for counts in many directions...eg 230 to 320 degrees! There are many stars in the 3D plot but none int he telescope view. I do not have limited viewing distance turned on.

John, I think you may be using either the Uniform 2 or Nonuniform 2 systems from the System menu.  In that case the telescope scans in a direction that is perpendicular to the plane of the star system, so you only see stars in two different directions.  Just use the System menu to switch to Uniform 1 (or one of the other systems) and this problem should go away.  Also, note that you can click and drag in the 3D view to get a better angle of view that will help you see what is going on.
