GATES ELLIPSE2D <2D-elliptical-gate-name>
(<x-coordinate> <y-coordinate> <rx> <ry>)1
(<x-coordinate> <y-coordinate> <rx> <ry>)2
...
(<x-coordinate> <y-coordinate> <rx> <ry>)ngates
where <rx>, etc. define the radii for each axis of the ellipse.
Each set of coordinates and radii defines an elliptical gate against which pairs of values may be tested in the commands section. If any gates overlap within a set earlier gates have precedence over later ones.
GATES ELLIPSE3D <3D-elliptical-gate-name>
(<x-coordinate> <y-coordinate> <z-coordinate> <rx> <ry> <rz>)1
(<x-coordinate> <y-coordinate> <z-coordinate> <rx> <ry> <rz>)2
...
(<x-coordinate> <y-coordinate> <z-coordinate> <rx> <ry> <rz>)ngates
Each set of coordinates and radii defines an ellipsoidal gate against which 3 values may be tested at a time in the commands section.
