Defines the specialization of a modulated scan mode.
Defined Terms:
The Meterset is delivered while the beam spot is at the specified position.
The delivery of the specified Meterset for the current spot position begins when the spot is at the previous spot position but the spot moves as quickly as possible to the current specified spot position where most of the Meterset is delivered.
The beam spot is delivered with uniform flux while traveling from one position to the next position (continuous).
Between control points the beam may be delivered by a combination of STATIONARY, LEAPING or LINEAR modes.
Required if Scan Mode (300A,0308) is MODULATED_SPEC.
See Section C.8.8.25.8.
The Scan Spot Position Map (300A,0394) and Scan Spot Meterset Weights (300A,0396) shall be used as follows.
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) = 20.
If Modulated Scan Mode Type (300A,0309) is STATIONARY or LEAPING:

(1.0, 2.0) |
(3.0, 2.0) |
(5.0, 2.0) |
(7.0, 2.0) |
(9.0, 2.0) |

Delivery Description:
The beam is positioned at Scan Spot Position (1.0, 2.0).
The beam is delivered with a Cumulative Meterset Weight of 5.
The beam is switched off or quickly moved and positioned at Scan Spot Position (3.0, 2.0).
The beam is delivered with a Cumulative Meterset Weight of 4.
The beam is switched off or quickly moved and positioned at Scan Spot Position (5.0, 2.0).
The beam is delivered with a Cumulative Meterset Weight of 6.
The beam is switched off or quickly moved and positioned at Scan Spot Position (7.0, 2.0).
The beam is delivered with a Cumulative Meterset Weight of 2.
The beam is switched off or quickly moved and positioned at Scan Spot Position (9.0, 2.0).
The beam is delivered with a Cumulative Meterset Weight of 3.
If Modulated Scan Mode Type (300A,0309) is LINEAR:
Position (X,Y) |
(1.0, 2.0) |
(3.0, 2.0) |
(5.0, 2.0) |
(7.0, 2.0) |
(9.0, 2.0) |

Delivery Description:
The beam is positioned at Scan Spot Position (1,.0 2.0).
The beam is continuously delivered with a Cumulative Meterset Weight of 4, while being moved from Scan Spot Position (1.0, 2.0) to Scan Spot Position (3.0, 2.0).
The beam is continuously delivered with a Cumulative Meterset Weight of 6, while being moved from Scan Spot Position (3.0, 2.0) to Scan Spot Position (5.0, 2.0).
The beam is continuously delivered with a Cumulative Meterset Weight of 7, while being moved from Scan Spot Position (5.0, 2.0) to Scan Spot Position (7.0, 2.0).
The beam is continuously delivered with a Cumulative Meterset Weight of 3, while being moved from Scan Spot Position (7.0, 2.0) to Scan Spot Position (9.0, 2.0).
