Constructor Detail

MoonAzimuth

public MoonAzimuth(Map<String,String> info)

Constructs a new sidereal time object. Note that this global can only function correctly after the time and longitude have been registered.

Method Detail

rescanned

public double rescanned(String key,
                        String old,
                        String newval)

As any parameter depending instance we fail if the parameter we depend on is now a different one.

Specified by:

rescanned in interface Reloadable

Overrides:

rescanned in class AbstractParameter

setValue

public Number setValue(Number val)
                throws UnsupportedOperationException

Sets the moon height. It is a read-only variable, therefore this method throws an UnsupportedOperationException.

Specified by:

setValue in interface Value

Throws:

UnsupportedOperationException

getValue

public Number getValue()

Returns the actual height of the sun over the horizon. For convenience, the returned value is in degrees not in radians. If either of the three parameters denoting the sidereal time, the latitude of the site or the ecliptical longitude of the sun is missing, null is returned.

Specified by:

getValue in interface Value

registerParameter

public void registerParameter(Parameter what)

Registers the required additional globals for the sidereal time. For this particular object, latitude and UT is required. Note that the argumental global is checked for being of instance types of Time or Longitude, rather than querrying for the global name.

Specified by:

registerParameter in interface ParameterDepending

getAscendTime

public Double getAscendTime(Number hsol)

Returns the remaining time in ms. For the ascend the solution of the hour angle that satisfies dh/dt>0 is used to derive the remaining time. The solar position is considered inmutable.

Specified by:

getAscendTime in interface Increasing<Number>

Parameters:

hsol - The value in the future.

Returns:

A double carrying the remaining time or null if the time cannot be calculated.

calcTime

private Double calcTime(double az,
                        double phi,
                        double dec)

Calculates the remaining time until a given az is reached. Always uses the ascend time of the hour angle definition. If the target definition handed over is null, the non-target depending version of the ascend time of tau is used.

Parameters:

az - Target azimuth of object in degrees.

phi - Latitude in degrees.

dec - Declination of object in degree.

target - If non-null the target depending time is used.

getFormatted

public String getFormatted()

Returns the formatted moon height value. It is a string giving the moon z in deg, min, and sec.

Specified by:

getFormatted in interface Parameter

Overrides:

getFormatted in class AbstractParameter
