>> Removes any points that are within the specified point range and specified
|
|
volume of space. This is done in Cartesian (**xyz**), cylindrical (**rtz**),
|
|
or spherical (**rtp**) coordinates. It should be noted that in cylindrical
|
|
coordinates, theta is the angle in the XY- plane with respect to the x-axis,
|
|
while in spherical coordinates theta is the angle with respect to the Z-axis
|
|
and phi is the angle in the XY-plane with respect to the X-axis. In
|
|
cylindrical coordinates the cylinder always lines up along the z axis; use the
|
|
**coordsys **command before issuing the **rm **command if the points to be
|
|
removed are not aligned with the z-axis; then issue a final **coordsys**
|
|
command to return to normal. Also note that the points that are removed become
|
|
dudded out (point type set to 21) and are not removed from the data array.
