Abstract

The method of least squares, as used in the Harmonic Shallow Water Correction (HSWC) technique by A min (1977), is adapted under restrictions of fixed data length and specified constituents, imposed by Doodson’ s (1957) method. It is shown that the technique provides a quick and simple method of computing HSWC coefficients. Also some simple graphic explanation of the criteria for selection of data length, essential to resolve constituents having given speeds, is provided.
