function clean

Performs "cleaning" of the input image. This iterative deconvolution algorithm searches for the global maximum in the image, shifts the psf to that position and subtracts a scaled psf (multiplied by the gain). The subtracted flux is added to a delta map at the position of the maximum (this is the clean map). Note that clean does not conserve the total flux in the image.

Syntax
result = clean(IMAGE, PSF, N, GAIN [, variable SUB])

Arguments

IMAGE:   input map to be cleaned (dirty map)

PSF:   Point spread function (dirty beam)

N:   Number of iterations

GAIN:   Loop gain factor

SUB:   Optional, the variable SUB will contain an image in which the sources are subtracted
