congen is a C++ library for generating the speeds, equilibrium arguments,
and node factors of Darwin-style tidal constituents more or less as defined
in SP 98:
Manual of Harmonic Analysis and Prediction of Tides. Special Publication
No. 98, Revised (1940) Edition (reprinted 1958 with corrections;
reprinted again 1994). United States Government Printing Office, 1994.
Additionally, libcongen provides limited support for approximating
Doodson-style tidal constituents within the infrastructure of the former.
The Doodson approach is discussed in the following publication:
Foreman, M.G.G., 1977. Manual for Tidal Heights Analysis and Prediction.
Pacific Marine Science Report 77-10, Institute of Ocean Sciences,
Patricia Bay, Sidney, B.C. (2004 revision).
The Congen header file is intended to be self-documenting with regards to use
of the interface, assuming that one has access to SP 98 and a general
understanding of the subject matter.
