Table 26: Criteria for pixel to be entered in failure map

Pixel location is a fail in map if

Small average < Large average - (1.2% of Large average)

or

Small average > Large average + (1.2% of Large average)

VV6501

The contents of the fail map determine whether the sensor fails the physical aberration test. The fail

criteria are given in Table 27 below:

Table 27: Physical aberration test fail criteria

Fail physical aberration test if

> 82 contiguousa pixel entries in the failure map

a. An example of contiguous pixels entries is given in Figure 36

Figure 36: Contiguous pixels example

The group of pixels

enclosed in the circle

are contiguous, that is

every pixel in the group

is attached to at least

one neighboring pixel.

The other pixel entries

shown in the figure

are non contiguous as

they have no touching

neighbors.
