Description

All components positioned after this one are rotating at frequency 'nu' with
phase 'phase'. Use the Derotator component to put back the model steady.
The rotation is performed w.r.t. the position of the component, along a chosen
main axis (use directon=1 for x, direction=2 for y, direction=3 for z).

Default rotation axis is vertical axis / 'y'.

Example:
R=Rotator(nu=14, phase=0)
...
DR=Derotator(rotator=R)
AT (0,0,0) RELATIVE R

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
nu	Hz	Rotation frequency (round/s) in the rotating option (vertical axis)	0
phase	deg	Phase shift	0
direction	1	Rotation axis selection 1=x, 2=y, 3=z	2

AT (	,	,		) RELATIVE		Generate
ROTATED (	,	,		) RELATIVE
