Based on an analysis of measurements of Centaurus A as described in Zemcov et al. (2009) - arxiv:0908.2431. Please reference this paper in works using these data.

For this release we provide maps of Cen A at 100 and 150 GHz in T, Q and U fully corrected for polarization leakage and polynomial filtering. The QuaD maps follow the IAU polarization convention. Both raw and Richardson-Lucy deconvolved maps (as idealized input to general instrument simulations) are available. Data are provided as standard .fits files with 1.2 arcmin pixel size and calibrated in micro K(CMB); astrometry and other standard meta data is included in the headers. Per pixel uncertainties in the square degree region centered on the source are listed in the third (random uncertainties) and fourth (systematic uncertainties) columns.
