Thanks. This is useful but I am trying to get the French coefficients to use with the newly free SHOM current data that they have made available. The same data that they use in their paper atlases of tidal currents.
I don't know much about it, but in the attached file (from the shom) would the figures indicated for each latitude/longitude correspond to what you are looking for?
Mike,
The file is too heavy, it does not pass.
You can find it in the message I sent you 3 days ago (the file is called Atlas.cur) but I don't know if that's what you're looking for...
