window must fit inside the current pan window limits retrieved with the PNW? command.
Detector coordinates are used to position the origin location which in turn defines the World
Coordinate system. Detector coordinates also are used to define the location of the frame data
capture windwo which in turn defines the Frame Coordinate system.
10.7.2.1 DIS - Set Manual Origin Location
The Origin location can be set anywhere inside the :PNW? limits. Since the Origin location
defines world coordinates, there is no way for you to associate a particular world coordinate with
the manual origin location. The Origin location must be defined in terms of the detector
coordinate system.
See section 9 regarding the World Coordinate system and the LBA-PC online help for more
information about Origin Locations.
The following example describes how to enable the manual origin and set the manual origin
location to the center of the detector. The center of the detector in this example is at
(112+744)/2 and (32+512)/2.

Another technique that you can use to position the origin in manual origin mode is to move the
cursors to the desired location (:CUR) and send the :ORG command which sets the manual origin
to the current cursor location.

The PAN command specifies the upper left corner of the capture window. The entire capture
