process

public void process(Image[] input,
                    Image output,
                    int[] osource,
                    Sampler samp,
                    DepthSampler dSampler)

Populate the pixel values of the output mosaic. Note that the output image is assumed to be created prior to the mosaic call since its WCS will have been used extensively.

Specified by:

process in class Processor

Parameters:

input - An array of input images.

output - The image whose data is to be filled.

osource - An integer array giving the source image to be used for the output pixels. Note that depending upon the mosaicker used, source may be dimensioned as either nx*ny or (nx+1)*(ny+1).

samp - The sampler to be used to sample the input images.

dSampler - The sampler (if any) in the energy dimension.

addPixels

protected void addPixels(java.lang.String name,
                         int count)

setUsedImages

protected void setUsedImages()

updateHeader

public void updateHeader(nom.tam.fits.Header h)

Describe the mosaicking of the image .

Specified by:

updateHeader in class Processor

ordinalSuffix

public static java.lang.String ordinalSuffix(int n)

Find appropriate ordinal suffix for a given integer.
