The value for DIRECTION
Angle between the polarizing and operating quantity
is not in any of the defined sectors.
0 = unknown
Angle between the polarizing and operating quantity
is in the forward sector.
1= forward
Angle between the polarizing and operating quantity
is in the reverse sector.
2 = backward
Angle between the polarizing and operating quantity
is in both the forward and the reverse sectors, that is,
the sectors are overlapping.
3 = both
