CALIM 2010: 5th SKA Workshop on Calibration and Imaging
The CALIM series of workshops focuses on progress in algorithms, software and computing aimed at solving the challenges in calibration and imaging requirements of the SKA, its pathfinders and other major new radio telescopes such as EVLA, ALMA, LOFAR, ASKAP, MeerKAT, MWA, LWA, and eMERLIN.Tags: workshop, calibration, imaging, ska

Absolute polarization angle calibration using polarized diffuse Galactic emission observed by BICEP
We present a method of cross-calibrating the polarization angle of a polarimeter using BICEP Galactic observations. \bicep\ was a ground based experiment using an array of 49 pairs of polarization sensitive bolometers observing from the geographic South Pole at 100 and 150 GHz. The BICEP polarime...Tags: wmap, calibration, bicep
