  • Origin: ESRF
  • Date: November 6, 2013
  • Version: 1.0

Description

Changes direction of the photon to a random direction
towards the specified target area.
To be used in coherent simulations, preferably with
the SPLIT keyword.

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
dist m : distance to target 0.0
focus_xw m : x-width of target 0.0
focus_yh m : y-height of target 0.0
focus_x0 m : x-center of target 0.0
focus_y0 m : y-center of target 0.0
focus_absolute : Flag - if non-zero, focus_x0 and focus_y0 are in absolute (lab) coordinates. 1
