Interface PromptMatching

All Known Implementing Classes:

PromptSpillage, PromptVanish

public interface PromptMatching

Implementers can deliver a pixel shift directly from a reduced image. This can be useful for auto-guiders once the acquisition on the pivotal (hot pixel) point is completed.

Method Detail

promptShift

Vector2D promptShift(Point2D hotpix,
                     MImageHDU reduced,
                     Rectangle readout,
                     Dimension bin)
              throws CannotMatchException

Parameters:

hotpix - 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

Throws:

AmbiguousPatternException

NoStarException

CannotMatchException
