Crystal element - diffraction plane angle does not have any effect on the calculation results #4

Closed mrakitin closed 8 years ago

mrakitin commented 8 years ago

It looks like the change of the diffraction plane angle does not cause any change in the final results of the intensity report after propagation. This angle does cause change of the normal and tangential vector components, but they don't change the result. Need to discuss with Oleg.

The angle changes the intensity, the problem is that the negative angle with the same absolute value produces the same intensity as positive angle.

mrakitin commented 8 years ago

After some experimenting with parameters it looks like the sign of the angle causes change of the intensity:

+2 rad:

intensity-at-watchpoint-report-21m_ 2

-2 rad:

intensity-at-watchpoint-report-21m_-2

@DmitrySmalyuk, please have a look.
