Attribute: Tide - value of harmonic constituents
Attribute type: A
Harmonic constituents are the harmonic elements in a mathematical expression for the tide producing force and in the corresponding formula for the tidal curve. Each constituent represents a periodic change or variation in the relative positions of the earth, moon and sun.
the first is the number of columns (C, always 2) and the second is the number of rows (R). The next value(s) (C times) indicates the name(s) of the columns, and the next value(s) (R times) indicates the name(s) of the rows (ie constituents). Here after follow the values (C x R times) of amplitude and phase.
the following example encodes the amplitude and the phase for M2, S2, K1 and O1.
amplitude phase M2 0.962 165 S2 0.361 243 K1 1.223 097 O1 0.875 143
