java.lang.Object

java.util.EventObject

util.rmi.RmiEvent

stella.MessageEvent

stella.CommandEvent

stella.command.DitherTelescope

All Implemented Interfaces:

Serializable, TelescopeCommand

public class DitherTelescope
extends CommandEvent
implements TelescopeCommand

The command sent from the adapter to the telescope to allow fine-guiding. The two offsets are pixel offsets in x/y direction of the guiding CCD, diveded by the scale factor of the guiding CCD.
This command is not intended for direct communication between the SCS and the telescope, but rather for permanent update of the guiding offset as deduced by the adapter.

private double deoffset

The offset in altitude, in degrees.

Constructor Detail

DitherTelescope

public DitherTelescope(Object src)

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

DitherTelescope

public DitherTelescope(Object src,
                       String id,
                       long time)

Constructs a new offset telescope command. The command only gets valid when either its parseLine(java.lang.String[]) or the setOffset(double, double) method are called.
To mark both offsets invalid, NaN is assigned to them.

Method Detail

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.

setOffset

public void setOffset(double xoff,
                      double yoff)

Sets the offsets in azimuth and height.

Parameters:

xoff - Offset in azimuth, degrees.

yoff - Offset in altitude, degrees.

getOffsetRa

public double getOffsetRa()

Returns the x-offset of the target star. If the command is invalid, NaN is returned.

getOffsetDe

public double getOffsetDe()

Returns the y-offset of the target star. If the command is invalid, NaN is returned.
