Attribute: Sector limit two
Attribute type: F
A sector is the part of a circle between two straight lines drawn from the centre to the circumfe rence. (Advanced Learner's Dictionary, 2nd Edition)
The sector limit 2 specifies the second limit of the sector. The order of sector limit 1 and sector limit 2 is clockwise around the central object (e.g. a light).
ENC Condition:# Must be encoded for LIGHTS objects that are sector lights.
INT 1: IP 40;
M-4: 475; 475.1;
Minimum Value: 0
Maximum Value: 360
Resolution: 0.01 degree
Conversion factor: one tenth of a second = 0.000028 degree.
220 for a sector orientation of 220 degrees.
The values given to the common limits of adjacent sectors should be identical.
The orientation of bearing is from seaward to the central object. This to the method used in 'List of Lights' publications.
A generic term such as 'to shore' cannot be used; a specific bearing must be encoded. Where a light sector limit is defined as 'to the shore', it should be encoded using a value that ensures that, when the limit is drawn, it will fall entirely on land.
