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...
W-band prototype of platelet feed-horn array for CMB polarisation measurements
platelet feed-horn array polarisation measurements
2011/9/28
We present the design and performance of a 2x2 prototype array of corrugated feed-horns in W-band. The module is fabricated using a so-called "platelet" technique by milling Aluminum plates. This tech...
