nodal_adj {TideHarmonics} | R Documentation |
Calculates nodal corrections from astronomical longitudes (lambdas). Mainly for internal use.
nodal_adj(lambp, lambN, lambph, indegree = TRUE, outdegree = TRUE)
lambp |
Lambdas for the lunar perigee (p). |
lambN |
Lambdas for the lunar nodal (N). |
lambph |
Lambdas for the sun's perihelion (ph). |
indegree |

A list with two elements, where both are matrices with 409 rows,
which correspond to the 409 harmonic constituents available in the
package. The first element fn
gives the amplitude corrections.
The second element un
gives the phase corrections.
