Description
Basically the "imerg" algorithm of AIPS and SDE, or the "feather"
algorithm of MIRIAD, we regrid the total power (or low resolution)
image onto the interferometer (or high resolution) image, Fourier
transform both the interferometer and single dish images, down weight
the Fourier transform of the interferometer image by 1.0 - FT(low res psf),
add the weighted interferometer Fourier plane to the single dish Fourier
plane, and transform back into the image plane.
The tapering is by the transform of a point spread function. If lowpsf
is specified, that image is used, otherwise the appropriate telescope
beam is used. The point spread function for a single dish image may be
calculated using approximatepsf.
