Interface AcquisitionControlling

All Superinterfaces:

CcdControlling, ListenerControlling, Remote

All Known Implementing Classes:

AcquireMaster, AdapterMaster, AuxiliaryMaster, OffAxisMaster, PinholeViewingMaster

public interface AcquisitionControlling
extends ListenerControlling, CcdControlling

Defines remote access for the acquisition and guiding. Extends the standard CcdControlling interface. This methods always refer to the acquisition CCD. If a second, different guiding CCD is present, use the appropriate methods in this interface

Method Summary

Modifier and Type	Method and Description
boolean	center(double[] ra, double[] de, float[] m, float[] bv) Centers a field-of-view on the guider's predefined center.
boolean	hotPixelShift(double dx, double dy) Shifts the hot pixel from its default position by the stated amount in CCD pixel.
boolean	hotPixelShiftGuide(double dx, double dy) Shifts the hot pixel from its default position by the stated amount in CCD pixel.
boolean	initGuider() Initializes the guider and prepares it for a new guider loop.
boolean	offsetAzAlt(double daz, double dalt) Offsets the telescope by a certain amount in az/alt.
boolean	offsetXY(int dx, int dy) Offsets the telescope by a certain amount in x/y as seen on the acquisition CCD.
boolean	readoutGeometryGuide(Rectangle window, int xbin, int ybin) Sets the read-out geometry on the guider CCD only
boolean	resetCcd() Tries to reset the acquisition CCD.
boolean	resetCcdGuide() Tries to reset the acquisition CCD.
boolean	singleShotGuide(File fits, double texp) Takes a single exposure with the given exposure time in second.
boolean	startGuiding() Starts the auto-guider.
boolean	stopGuiding() Stops the guiding if active.

Method Detail

center

boolean center(double[] ra,
               double[] de,
               float[] m,
               float[] bv)
        throws RemoteException

Centers a field-of-view on the guider's predefined center.

Throws:

RemoteException

offsetXY

boolean offsetXY(int dx,
                 int dy)
          throws RemoteException

Offsets the telescope by a certain amount in x/y as seen on the acquisition CCD. The offset should be applied such that a star at x0, y0 is seen at x0+dx, y0+dy after the offset.

Parameters:

dx - Difference in pixel

dy - Difference in pixel

Throws:

RemoteException

offsetAzAlt

boolean offsetAzAlt(double daz,
                    double dalt)
             throws RemoteException

Offsets the telescope by a certain amount in az/alt.

Throws:

RemoteException

hotPixelShift

boolean hotPixelShift(double dx,
                      double dy)
               throws RemoteException

Shifts the hot pixel from its default position by the stated amount in CCD pixel.

Throws:

RemoteException

hotPixelShiftGuide

boolean hotPixelShiftGuide(double dx,
                           double dy)
                    throws RemoteException

Shifts the hot pixel from its default position by the stated amount in CCD pixel.

Throws:

RemoteException

readoutGeometryGuide

boolean readoutGeometryGuide(Rectangle window,
                             int xbin,
                             int ybin)
                      throws RemoteException

Sets the read-out geometry on the guider CCD only

Parameters:

window -

xbin -

ybin -

Returns:

Throws:

RemoteException

singleShotGuide

boolean singleShotGuide(File fits,
                        double texp)
                 throws RemoteException

Takes a single exposure with the given exposure time in second. The data is saved in FITS format to the provided file.

Throws:

RemoteException

resetCcd

boolean resetCcd()
          throws RemoteException

Tries to reset the acquisition CCD.

Throws:

RemoteException

resetCcdGuide

boolean resetCcdGuide()
               throws RemoteException

Tries to reset the acquisition CCD.

Throws:

RemoteException

initGuider

boolean initGuider()
            throws RemoteException

Initializes the guider and prepares it for a new guider loop.

Throws:

RemoteException

startGuiding

boolean startGuiding()
              throws RemoteException

Starts the auto-guider. Does not center before.

Throws:

RemoteException

stopGuiding

boolean stopGuiding()
             throws RemoteException

Stops the guiding if active. Returns false on failure, not on guiding not active.

Throws:

RemoteException
