Class PixelOffset

java.lang.Object

java.util.EventObject

util.rmi.RmiEvent

stella.MessageEvent

stella.ErrorEvent

stella.error.PixelOffset

All Implemented Interfaces:

Serializable

public class PixelOffset
extends ErrorEvent

A status mesage from the adapter delivering the offset in x and y as determined from the guider camera. This offsets are not the offset fed into the telescope, these are determined by the PID control within the adapter. This status message should give you a rough impression of the offsets experienced and should be sent each time an offset was calculated. The ascii-line carries the two offsets as

   XPIX=[pixel] YPIX=[pixel]

Constructor Detail

PixelOffset

public PixelOffset(Object src)

Constructs a new adapter fwhm status message. The FWHM must be set after construction by a call to #setFWHMAndFlux.

Method Detail

parseLine

public boolean parseLine(String[] all)

Parses the command lines submitted with the adapter fwhm status. Extracts the #fwhm and the #flux using the Strings.parseNumbers(java.lang.String, java.lang.String[]) method.

Overrides:

parseLine in class ErrorEvent

Returns:

True, if parsing was successful.

getLine

public String[] getLine()

Returns the command lines as an string array. See also main class entry.

Overrides:

getLine in class ErrorEvent

Returns:

An array containing all command lines.

getHuman

public String getHuman()

Returns the human-readable part of the string. See also main class entry.

Overrides:

getHuman in class ErrorEvent

Returns:

A String holding a readable description of the error.

updateHuman

private void updateHuman()

Updates the human readable part of the status message. This means calling of ErrorEvent.setHuman(java.lang.String) with values constructed from the internal variables.

getOffsetX

public double getOffsetX()

Returns the value of the fwhm.

getOffsetY

public double getOffsetY()

Returns the value of the flux.

setOffsets

public void setOffsets(double x,
                       double y)

Sets both offsets.
