stella.adapter.AdapterUnit

stella.adapter.GuidingUnit

All Implemented Interfaces:

Cloneable, Initializable, PropertySupplying, ResourceSupplying

Direct Known Subclasses:

BeamSplitterGuider, OffAxisTracker, SpillageGuider

public abstract class GuidingUnit
extends AdapterUnit

A guiding unit has the ability to keep an instrument fine alligned during the exposure. Normally this is done with a helper CCD by keeping the target star alligned at a crosshair..

See Also:

Constant Field Values

increase

protected double increase

A value set from the outside signaling increased exposure time.

allowswitch

protected boolean allowswitch

If true, the guider is allowed to request a guider mode change.

offrecord

protected DataOutputStream offrecord

An object output stream were we serialize our alt/az offs in.

pidrecord

protected DataOutputStream pidrecord

An object output stream were we serialize our alt/az offs in.

Constructor Detail

GuidingUnit

protected GuidingUnit(Map<String,String> p)

Method Detail

setIncrease

protected void setIncrease(double afteracquire)

Sets the increase value.

setAllowSwitch

protected void setAllowSwitch(boolean modechange)

Sets the state of the allow switch. If this is true, the guider may issue request to change the guiding mode.

setOffsetStream

protected void setOffsetStream(DataOutputStream open)

Sets a stream that should be used to serialize the offset data into.

setPIDStream

protected void setPIDStream(DataOutputStream open)

Sets a stream that should be used to serialize the pids data into.

getExposureTime

protected abstract long getExposureTime()

Returns the guider exposure time, available after unit task.

createGuiderLoop

protected abstract TimerTask createGuiderLoop(long repeatperiod)

Creates the guider loop, which can be used as a timer task. This method must be called after the unit task was done without an error, and piped to the adapter masters timer. For the benefit of knowing the guider period, the adapter master hands over the period in ms at which the task will be scheduled.

requestMode

protected abstract void requestMode(String mode)

Requests the guiding mode as the identifier string.

getMode

protected abstract GuiderMode getMode()

Returns the currently active guider mode.
