Grid Non-Uniformity is calculated in accordance with the ISO 15415
specification. The Grid Non-Uniformity grading is defined as follows.
A (4.0) if GN ≤ 038
B (3.0) if GN ≤ 0.50
C (2.0) if GN ≤ 0.63
D (1.0) if GN ≤ 0.75
F (0.0) if GN > 0.75
When enabled, the Grid Non-Uniformity is attached to the symbol out-
put data as a value.

Unused ECC is calculated in accordance with the ISO 15415 specifica-
tion. The Unused ECC grading is defined as follows.
A (4.0) if UEC ≥ 062
B (3.0) if UEC 0.50
≥
C (2.0) if UEC ≥ 0.37
D (1.0) if UEC ≥ 0.25
F (0.0) if UEC < 0.25
When enabled, the Unused ECC is attached to the symbol output data
as a value.
