Serializable, RelativeOffset, TelescopeCommand
Direct Known Subclasses:
InitialOffsetTelescope

public class EncoderOffsetTelescope
extends OffsetTelescope
implements RelativeOffset

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.

Field Detail

NAN

private static final String NAN
The identifier in the string representation for invalid azimuth/h.

Constant Field Values

azimuth

private double azimuth
The azimuth of the telescope, Nan for invalid/not known.


height

private double height
The height of the telescope, Nan for invalid/not known.

Constructor Detail

EncoderOffsetTelescope

public EncoderOffsetTelescope(Object src)
Constructs a abort adapter telescope, grabbing the type from the class name and setting the command time to the current system time.


EncoderOffsetTelescope

public EncoderOffsetTelescope(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 OffsetTelescope.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.

Overrides:
getLine in class OffsetTelescope
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.

Overrides:
parseLine in class OffsetTelescope
Returns:
True, if parsing was successful.

setHeight

public void setHeight(double h)
Sets the height of the telescope, if currently known.


getHeight

public double getHeight()
Return the height of the telescope.


setAzimuth

public void setAzimuth(double a)
Sets the height of the telescope, if currently known.


getAzimuth

public double getAzimuth()
Return the height of the telescope.
