public Tide(int cTau,
            int cS,
            int cH,
            int cP,
            int cNprime,
            int cPs)
```
    Simple constructor.
    
    Parameters:
    
    cTau - coefficient for mean lunar time
    
    cS - coefficient for mean longitude of the Moon
    
    cH - coefficient for mean longitude of the Sun
    
    cP - coefficient for longitude of Moon mean perigee
    
    cNprime - negative of the longitude of the Moon's mean ascending node on the ecliptic
    
    cPs - coefficient for longitude of Sun mean perigee
  - Tide
```
public Tide(int doodsonNumber)
```
    Simple constructor.
    
    Parameters:
    
    doodsonNumber - Doodson Number
- Method Detail
  - getDelaunayMultipliers
```
public int[] getDelaunayMultipliers()
```
    Get the multipliers for Delaunay arguments (l, l', F, D, Ω).
    Beware that for tides the multipliers for Delaunay arguments have an opposite sign with respect to the convention used for nutation computation! Here, we obey the tides convention.
    
    Returns:
    
    multipliers for Delaunay arguments (l, l', F, D, Ω)
  - getDoodsonMultipliers
```
public int[] getDoodsonMultipliers()
```
    Get the multipliers for Doodson arguments (τ, s, h, p, N', ps).
    
    Returns:
    
    multipliers for Doodson arguments (τ, s, h, p, N', ps)
  - getDoodsonNumber
```
public int getDoodsonNumber()
```
    Get the Doodson number.
    
    Returns:
    
    Doodson number
  - getTauMultiplier
```
public int getTauMultiplier()
```
    Get the multiplier for the τ Doodson argument.
    This multiplier identifies semi-diurnal tides (2), diurnal tides (1) and long period tides (0)
    
    Returns:
    
    multiplier for the τ Doodson argument
  - getPhase
```
public double getPhase(BodiesElements elements)
```
    Get the phase of the tide.
    
    Parameters:
    
    elements - elements to use
    
    Returns:
    
    phase of the tide (radians)
  - getRate
```
public double getRate(BodiesElements elements)
```
    Get the angular rate of the tide.
    
    Parameters:
    
    elements - elements to use
    
    Returns:
    
    angular rate of the tide (radians/second)
  - equals
```
public boolean equals(Object object)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
