Method Detail

promptShift

public Vector2D promptShift(Point2D pinhole,
                            MImageHDU reduced,
                            Rectangle readout,
                            Dimension bin)

Specified by:

promptShift in interface PromptMatching

Parameters:

pinhole - The pivotal point.

reduced - The reduced frame from the ccd, i.e., bias subtracted and flatfielded if required, raw if sufficient

readout - The window on the chip.

bin - The binning used.

Returns:

A pixel shift

checkForStarInPinhole

                                      MImageHDU hdu,
                                      Rectangle readout,
                                      Dimension bin,

                               throws BasicFitsException

We check if a star is already vanishing in the pinhole.

Parameters:

pinhole - Pinhole position

hdu - fits image from guider CCD

readout -

bin -

box - Size that includes pinhole plus edge with signal

frame - Around box for background determination

readnoise -

frac - Average signal around pinhole is higher than background by this factor.

tot - Total signal around pinhole is higher than background by this factor.

Returns:

Throws:

BasicFitsException
