public class TauTarget extends AbstractTargetValue implements TargetDependIncreasing, ParameterDepending, Reloadable
Value contract, the quantity returned is in degrees from -180 to
+180. Two other globals must be registered, SiderealTime and
RaTarget.

TauTarget(Map<String,String> info)
Constructs a new tau target object.
|
| Modifier and Type | Method and Description |
|---|---|
private static double |
calculate(double ratarget,
double sidtime)
Calculates the hour angle using the current sidereal time and the handed
over right ascension.
|
private Long |
calculateTime(Number until,
Number current)
Calculates the remaining time out of the target tau and the current tau.
|
Long |
getAscendTime(Number until)
Returns the remaining time in ms, always > 0.
|
Long |
getAscendTimeFor(TargetDefinition target,
Number until)
Returns the remaining time in ms, always > 0.
|
Object |
getForAfter(TargetDefinition star,
Double span)
Calcualtes the tau this target will have in the solar time-span passed
over to it.
|
Object |
getForBefore(TargetDefinition star,
Double span)
Calcualtes the tau this target had in the solar time-span passed over to
it.
|
Number |
getForTarget(TargetDefinition star)
Gets the declination of the target star.
|
Number |
getValue()
Returns the actual target's hour angle in degrees, wrapped into a Double.
|
void |
registerParameter(Parameter what)
Registers the required additional globals for the tau target.
|
void |
registerTarget(TargetDefinition star)
Registers a star to this parameter.
|
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.
|
Number |
setValue(Number val)
Sets the hour angle of the actual target.
