Method Detail

getAcquisition

Acquisition getAcquisition()

Gets the acquisition instance.

fineAcquisition

Vector2D fineAcquisition(Acquisition ag,
                         TransparencyMeasuring prior)
                  throws NoShiftException,
                         ConfigurationException

This method is called to conduct an entire fine acquisition cycle. During fine Acquisition, the #fineShift(Rectangle, Dimension, double, MImageHDU, AcquisitionAndGuiding) method will be called repeatedly.

Parameters:

ag -

Returns:

Throws:

NoShiftException

ConfigurationException

fineShift

Vector2D fineShift(Rectangle readout,
                   Dimension bin,
                   double expt,
                   MImageHDU reduced,
                   Acquisition ag)
            throws NoShiftException,
                   ConfigurationException

This method should return a pixel shift from checking the apparent position through an acquisition camera. It will be converted into a telescope offset using a RayPath assigned to the acquisition unit.

Returns:

A pixel shift in x/y CCD coordinates.

Throws:

ConfigurationException

NoShiftException
