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	initGuider() Initializes the guider and prepares it for a new guider loop.
boolean	offsetAzAlt(double daz, double dalt) Offsets the guider by a certain amount in az/alt on the guider CCD.
boolean	offsetXY(int dx, int dy) Offsets the guider by a certain amount in x/y on the guider CCD.
boolean	singleShot(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 guider by a certain amount in x/y on the guider 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 guider by a certain amount in az/alt on the guider CCD.

Throws:

RemoteException

singleShot

boolean singleShot(double texp)
            throws RemoteException

Takes a single exposure with the given exposure time in second. No way to specify a save-file or to tell whether the shot is saved at all, this is implementation specific.

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 no centering before.

Throws:

RemoteException

stopGuiding

boolean stopGuiding()
             throws RemoteException

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

Throws:

RemoteException
