**RM**

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.

The other options are:

geometry – **xyz**, **rtz**, **rtp**

ifirst,ilast,istride – point range to search

xmin, ymin, zmin – minimums of geometry type coordinates

xmax, ymax, zmax – maximums of geometry type coordinates

xcen, ycen, zcen – center of removal space for geometry

xscale, yscale, zscale – scaling factors for geometry limits

**FORMAT:**

**rm** / geometry
/ifirst,ilast,istride/xmin,ymin,zmin/xmax,ymax,zmax/ xcen,ycen,zcen
/ [xscale,yscale,zscale]

**EXAMPLES:**

```
rm/xyz/1,0,0/2.,2.,2./4.,4.,4./0.,0.,0./
rm/rtz/1,0,0/0.,0.,0./1.,360.,10./0.,0.,0./
