Description

Kudryavtsev, S M (2004) tidal potential catalogue

Usage

ksm04

Arguments

Format

A data.frame The columns are:

index: the index
body: body generating the potential
degree: degree of the spherical harmonic development
order: order of the spherical harmonic development, k1 = integer argument number for the mean local Moontime, period 24 hours 50 min.
k02: integer argument number for the mean longitude of the Moon, period 27.3 days.
K03: integer argument number for the mean longitude of the Sun, period 365.25 days.
K04: integer argument number for the mean longitude of the lunar perigee, period 8.8 years.
K05: integer argument number for the negate mean longitude of the lunar ascending node, period 18.6 years.
K06: integer argument number for the mean longitude of the solar perigee, period 20942 years.
K07: integer argument number for the mean longitude of Mercury, period 88 days.
K08: integer argument number for the mean longitude of Venus, period 225 days.
K09: integer argument number for the mean longitude of Mars, period 1.88 years.
K10: integer argument number for the mean longitude of Jupiter, period 11.86 years.
K11: integer argument number for the mean longitude of Saturn, period 29.4 years.
frequency: frequency of the tidal wave at J2000 in degree per hour.
C0: COS-coefficient of the tidal potential in 10^-10 m^2/s^2. The C0 coefficient has to be multiplied with the COS of the argument.
S0: SIN-coefficient of the tidal potential in 10^-10 m^2/s^2. The S0 coefficient has to be multiplied with the SIN of the argument.
C1: t*COS-coefficent of the tidal potential in 10^-10 m^2/s^2 per Julian century. The C1 coefficient has to be multiplied with the time difference between the epoch and J2000 (in Julian centuries) and with the COS of the argument.
S1: t*SIN-coefficent of the tidal potential in 10^-10 m^2/s^2 per Julian century. The S1 coefficient has to be multiplied with the time difference between the epoch and J2000 (in Julian centuries) and with the SIN of the argument.
C2: t*COS-coefficent of the tidal potential in 10^-10 m^2/s^2 per Julian century. The C1 coefficient has to be multiplied with the time difference between the epoch and J2000^2 (in Julian centuries) and with the COS of the argument.
S2: t*SIN-coefficent of the tidal potential in 10^-10 m^2/s^2 per Julian century. The S1 coefficient has to be multiplied with the time difference between the epoch and J2000^2 (in Julian centuries) and with the SIN of the argument.
name: Darwin name of the tidal wave (for very few main tidal waves available only)
amplitude: amplitude of the tidal wave at J2000
frequency_cpd: frequency of the tidal wave at J2000 in cycles per day
