- 1. add wake, convert (3. column)
- Preparation for CSRtrack:
The dog-leg is vertical, but CSRtrack is written for motion in the horizontal plane; therefore the input distribution is flipped by 90 degrees and the output distribution is flipped back.
See a) in the legend for CSRtrack calculation in principle.
