Method Detail

getFromURL

public static MFits getFromURL(URL durl)
                        throws IOException,
                               HeaderParsingException,
                               BasicFitsException

Reads an mfits object from an URL. No open connection remaining.

Parameters:

durl -

Returns:

null if no URL was given, otherwise the mfits.

Throws:

IOException

HeaderParsingException

BasicFitsException

mergeAll

public static Collection<MHeaderCard> mergeAll(MFits f)

skipToNoneEmptyImage

public static MImageHDU skipToNoneEmptyImage(MFits fits,
                                             int minskip)

Just to provide a method that will have identical signature to getHDUofType

Parameters:

fits -

minskip -

Returns:

getTrueFrame

public static double[] getTrueFrame(MImageHDU hdu,
                                    Rectangle act,
                                    int thick,
                                    boolean check)
                             throws BasicFitsException

Throws:

BasicFitsException

getTrueQuadrantsFrame

public static Map<MFitsTools.Quadrants,double[]> getTrueQuadrantsFrame(MImageHDU hdu,
                                                                       Rectangle active,
                                                                       int thick)

Extracts a frame at the inside of the active window and splits it into the four quadrant designations MFitsTools.Quadrants. All four list have the same amount of data, regardless if even or odd width/height are used (points may be contained in two quadrants, though). The shape of each quadrant can be depicted as an 'balanced' L.

Throws:

BasicFitsException

Takes a list of image hdu and returns only those that have data and match the first HDU in size.

Parameters:

all -

size - If null, first image HDU is used for size.

Returns:

equalSize

public static List<MImageHDU> equalSize(List<MImageHDU> all,
                                        ArrayLayout size)

Takes a list of image hdu and returns only those that have data of the specified size.

Parameters:

all -

size - May not be null

Returns:
