Attribute: Signal sequence
Acronym: SIGSEQ Code: 143
Attribute type: A
Definition:
The sequence of times occupied by intervals of light and eclipse for all 'light characteristics'
except
for occulting where the sequence of times is occupied by intervals of eclipse and light.
Indication:
Unit for value of intervals: second (s)
resolution: 0.01 s
Format:
LL.L + (EE.E)
Example:
00.8+(02.2)+00.8+(05.2)
The above example encodes a signal sequence with two intervals of light and two intervals of
eclipse.
For occulting lights, the 'signal sequence' is indicated using a fixed format to encode the values
of
intervals of eclipse (E) and (L).
Format:
(EE.E)+LL.L
Example:
(00.8)+02.2+(00.8)+05.2)
The above example encodes a signal sequence with two intervals of eclipse and two intervals of
light.
Remarks:
The 'signal sequence' for all 'light characteristics' except for occulting is indicated using a fixed
format
to encode the value of intervals of light (L) and eclipse (E).
Attribute: Tidal stream - panel values
Acronym: TS_TSP Code: 159
Attribute type: A
Indication:
The direction in degrees and velocity in knots are encoded in pairs. Each value separated by a
comma.
