tidedata: Tidal Constituent Information

Description

The tidedata dataset contains Tide-constituent information that is use by tidem() to fit tidal models. tidedata is a list containing

const

a list containing vectors name (a string with constituent name), freq (the frequency, in cycles per hour), kmpr (a string naming the comparison constituent, blank if there is none), ikmpr (index of comparison constituent, or 0 if there is none), df (frequency difference between constituent and its comparison, used in the Rayleigh criterion), d1 through d6 (the first through sixth Doodson numbers), semi, nsat (number of satellite constituents), ishallow, nshallow, doodsonamp, and doodsonspecies.

sat

a list containing vectors deldood, phcorr, amprat, ilatfac, and iconst.

shallow

a list containing vectors iconst, coef, and iname.

Apart from the use of d1 through d6, the naming and content follows T_TIDE (see Pawlowicz et al. 2002), which in turn builds upon the analysis of Foreman (1978).
