4. Multi-frequency deconvolution - MFCLEAN
Next: Other deconvolution tasks Up: Image Deconvolution Previous: Computation . If you have used multi-frequency synthesis in the imaging stage, you will have to have considered a fly in the ointment - the flux density of the source will vary with frequency (as well as spatially). For detection and low dynamic-range work, mild spectral variation can generally be ignored. ... The Miriad deconvolution task mfclean can be used to avoid this distortion. ...
