Released Grading Record
Border mode calculates centering and yaw from the recorded corner-border measurements. Landmark mode calculates LR/TB from direct design-landmark distances and records yaw independently when a reliable horizontal or vertical reference is available.
Dimensional measurements are recorded manually in millimeters and are subject to an approximate ±0.1 mm measurement uncertainty. Clockwise yaw is positive (+); counterclockwise yaw is negative (−). “Not measured” means no reliable yaw reference was available.
