FIGURE 6.4-2. Crossing Data with Second Dimension Value

2 Dim Level Crossing Example: Figure 6.4-2 depicts the data input for a two

dimensional level crossing histogram that has three level crossing values (1,

1.5, 3) and three SecondDim values (1.25, 2.25, 3.25). This results in a level

crossing histogram having 9 bins. In this example, a count would go to bin:

Bin(1,1) when LC Crosses 1 and 2nd Value < 1.25

Bin(1,2) when LC Crosses 1 and 1.25 ≤ 2nd Value < 2.25

Bin(1,3) when LC Crosses 1 and 2.25 ≤ 2nd Value < 3.25

Bin(2,1) when LC Crosses 1.5 and 2nd Value < 1.25

Bin(2,2) when LC Crosses 1.5 and 1.25 ≤ 2nd Value < 2.25

Bin(2,3) when LC Crosses 1.5 and 2.25 ≤ 2nd Value < 3.25

Bin(3,1) when LC Crosses 3 and 2nd Value < 1.25

Bin(3,2) when LC Crosses 3 and 1.25 ≤ 2nd Value < 2.25

Bin(3,3) when LC Crosses 3 and 2.25 ≤ 2nd Value < 3.25

Using the sample data depicted in Figure 6.4-2, the values loaded in to the

LevelCrossing bins are as listed under Action below:
