Feathering: Combine two images using the Fourier Addition: The algorithm converts each image to the gridded visibility plane, combines them, and reconverts them into an combined image. The images must have a well-defined beam shape (clean beam), given in the image, in order for feathering to work well. The two images must be on the same grid and have the same flux density normalization scale. Keyword arguments: imagename -- Name of output feathered image default: none; example: imagename='orion_combined' highres -- Name of high resolution (interferometer) image default: none; example: imagename='orion_vla.im' This image is often a clean image obtained from synthesis observations. lowres -- Name of low resolution (single dish) image default: none; example: imagename='orion_gbt.im' This image is often a image from a single-dish observations or a clean image obtained from a lower resolution synthesis observations.
