Direct Known Subclasses:

JMoveTelescope

public class MoveTelescope
extends CommandEvent
implements TelescopeCommand, TargetDepending, TargetDependingCommand, InitializerDepending, ParameterDepending

The move telescope command. It takes dom-elements of type star and scans its general section for the ra, dec, equinox, and proper motions to derive the actual position of the target star from it. The targets ra and dec, both in degrees in the actual equinox, are placed onto the command line.

Constructor Detail

MoveTelescope

public MoveTelescope(Object src)

Constructs a abort adapter telescope, grabbing the type from the class name and setting the command time to the current system time.

MoveTelescope

public MoveTelescope(Object src,
                     String type,
                     long time)

Constructs a move telescope command. Only the header is fully qualified with the provided argumnets. The command line can only be retrieved after a DTDConstants.OBJECT element has been registered to this command.

MessageEvent.isValid()

Method Detail

initWith

public void initWith(String focus)

Use to override the default setting of the derotator offset, following and usage. If any of the parts

• offset=double
• use=boolean
• follow=boolean

separated by colons is present, the derotator offset, follow and usage assume the inidicated behaviour, overriding the default settings of 0.0,false,true.
Example:
init="offset=10.0:follow=true"
Means that we use an offset of ten degrees and follow with the derotator during tracking

Specified by:

initWith in interface InitializerDepending

registerParameter

public void registerParameter(Parameter alt)

Register the derotator offset

Specified by:

registerParameter in interface ParameterDepending

registerTarget

public void registerTarget(TargetDefinition star)

Registers the target. We scan for the named setup with the ID #DEROTATOROFFSET. If this target does not allow the derotator offset, it is disabled.

Specified by:

registerTarget in interface TargetDepending

registerTargetProperties

public void registerTargetProperties(Object aim)

Calculates the command line from the star description delivered in the argument.

Specified by:

registerTargetProperties in interface TargetDependingCommand

setRaDe

public void setRaDe(double raset,
                    double deset)

Sets ra and dec.

getLine

public String[] getLine()

Returns the command line of the move telescope command.

Specified by:

getLine in class MessageEvent

Returns:

An array containing all command lines.

parseLine

public boolean parseLine(String[] all)

Parse the command line into ra and dec of the move command.

Specified by:

parseLine in class MessageEvent

Returns:

True, if parsing was successful.

getRa

public double getRa()

Returns the right ascension of the target star.

getDec

public double getDec()

Returns the declination of the target star.

getDerot

public double getDerot()

Returns the derotator offset.

isFollow

public boolean isFollow()

Returns true if the derotator should follow.

setFields

protected void setFields(double raext,
                         double decext,
                         double derotext,
                         boolean followext)

Daughter access to the ra, dec, derotator and follow fields.
