Fundamental Limitations of Pixel Based Image Deconvolution in Radio Astronomy
Deconvolution is essential for radio interferometric imaging to produce scientific quality data because of finite sampling in the Fourier plane. Most deconvolution algorithms are based on CLEAN which uses a grid of image pixels, or clean components. A critical matter in this process is the select...Tags: clean, convolution
