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.

References:

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 forma t to encode the value of intervals of light (L) and eclipse (E).
