java.lang.Object

stella.adapter.GuiderFrame

All Implemented Interfaces:

Guiding.RawFrame

public class GuiderFrame
extends Object
implements Guiding.RawFrame

An implementation of Guiding#RawFrame. A container to carry information on the readout parameter to the guider ccd.

Constructor Detail

GuiderFrame

public GuiderFrame()

Contructs a new GuiderFrame without info.

GuiderFrame

public GuiderFrame(Rectangle r,
                   Dimension bin,
                   File bfits,
                   long bexpose,
                   File dfits,
                   long dexpose)

Constructs a guider frame with all info. Some or all may be null.

GuiderFrame

public GuiderFrame(Rectangle r,
                   Dimension bin,
                   File bfits,
                   long bexpose,
                   File dfits,
                   long dexpose,
                   File ffits)

Constructs a guider frame with all info. Some or all may be null.

Method Detail

getReadoutFrame

public Rectangle getReadoutFrame()

Returns the readout frame. Null if invalid.

Specified by:

getReadoutFrame in interface Guiding.RawFrame

getBinning

public Dimension getBinning()

Returns the applicable binning on the ccd. If null, no special binning should be used. What that means is interpreted on the ccd-server side, but the most natural choice would be to use no binning.

Specified by:

getBinning in interface Guiding.RawFrame

getBiasFrame

public File getBiasFrame()

Returns the the bias frame that fits to the requested readout frame. The file should point to a fits file of equal size as the readout frame. If null, no bias reduction should be performed.

Specified by:

getBiasFrame in interface Guiding.RawFrame

getBiasTime

public long getBiasTime()

Returns the exposure time applicable for the bias fram which is important for shutterless system. Return -1 if no bias frame is available.

Specified by:

getBiasTime in interface Guiding.RawFrame

getDarkFrame

public File getDarkFrame()

Returns the the dark frame that fits to the requested readout frame. The file should point to a fits file of equal size as the readout frame. If null, no bias reduction should be performed.

Specified by:

getDarkFrame in interface Guiding.RawFrame

getDarkTime

public long getDarkTime()

Returns the exposure time applicable for the dark frame. Return -1 if no dark frame is available.

Specified by:

getDarkTime in interface Guiding.RawFrame

getFlatField

public File getFlatField()

Returns the flat-field frame, if applicable. Integration time on flat field frame is not important. It is impossible to create a consistent flat field on a shutterless system.
