A multiple-beam CLEAN for imaging intra-day variable radio sources
Methods: data analysis – Techniques: image processing – Radio continuum: general
2011/10/13
The CLEAN algorithm, widely used in radio interferometry for the deconvolution of radio images, performs well only if the raw radio image (dirty image) is, to good approximation, a simple convolution ...
MEM and CLEAN Imaging of VLBA Polarisation Observations of Compact Active Galactic Nuclei
CLEAN Imaging VLBA Polarisation Compact Active Galactic Nuclei
2011/10/10
The Maximum Entropy Method (MEM) for the deconvolution of radio interferometry images is mathematically well based and presents a number of advantages over the usual CLEAN deconvolution, such as appre...
How to make clean separation of CMB E and B mode from incomplete sky data
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
We have investigated CMB E/B decomposition of incomplete sky data. Noting E and B mode decomposition operators in real space involve differentials of CMB polarization, we point out we may make clean E...
