† _{White and black nonuniform pixel pair}
‡ _{The total spot count is the sum of 1) the numbers of nonuniform white pixels, nonuniform black pixels, and nonuniform white/black pixel pairs}
while the sensor is in the dark condition and 2) the number of nonuniform black pixels while the sensor is in the illuminated condition. The total
spot count will not exceed the values shown in this column.
