The Scan Spot Position Map (300A,0394) and Scan Spot Meterset Weights (300A,0396) shall be used as follows.

For a Modulated Scan Mode Type (300A,0309) value of LEAPING or LINEAR, switching off the beam shall be prescribed and reported using a Meterset Weight of zero at the next Scan Spot Position.

The following specifies for each value of Modulated Scan Mode Type (300A,0309) the definition of the map which is included in the Control Point 1 having Cumulative Meterset Weight (300A,0134) = 20, followed by a Control Point 2 having Cumulative Meterset Weight (300A,0134) = 40.

If Modulated Scan Mode Type (300A,0309) is STATIONARY:
