Tidal calculations - node factors and equilibrium arguments[edit]

Can't see that the calculations take account of node factors and equilibrium arguments. What I really want to know is how you can clauculate node factor and eq arg instead of looking em up in a table. Anyone got ideas? Mister Flash (talk) 18:19, 8 June 2009 (UTC)

After you get the frequencies from the Doodson numbers, you then do a Harmonic Analysis. The equalibrium arguments come out of the harmonic analysis with the amplitudes, and the nodal factors are from the terms fitting Beta_5. Drf5n (talk) 13:50, 18 May 2015 (UTC)
