All Implemented Interfaces:

Serializable

public class PidOffset
extends ErrorEvent

A status mesage from the adapter delivering the offset in az and alt as determined from the guider camera. These offsets are the offset fed into the telescope, as 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

   AZOFF=[arcsec] ALTOFF=[arcsec]

Constructor Detail

PidOffset

public PidOffset(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 StringTool.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.

getAzOff

public double getAzOff()

Returns the value of the fwhm.

getAltOff

public double getAltOff()

Returns the value of the flux.

setOffsets

public void setOffsets(double az,
                       double alt)

Sets the offsets.
