<div dir="ltr">This is merely a display oddity when gravity is simulated, as the ray moves in a parabola but only reports it’s position when scattered. You can view the horizontal plane where this effect does not occur. If you have a high horizontal divergence,
the scattering events are also more frequent and it is easier to see that the vertical movement is parabolic.</div>

<p>Dear all,</p>
<p>I'm just doing some tests with this component in preparation of parabolic and elliptic guides. I wonder whether somebody else has observed the strange behaviour I got just now. Attached is a simple test instr setup. I saw an asymetric intensity distribution
in y even with gravity "off". Doing a "trace" (see y-z panel attached) I saw that the rays are deflected vs -y at the entrance of the first parabola / ellipse.</p>
<p>A first glimpse into the code didn't tell me too much, where this could happen, but as far as I believe it shouldn't.</p>
<p>Any help is welcome.</p>
<p>Best regards,</p>
<p>Peter</p>
