Antenna instrumental polarization and its effects on <i>E</i>- and <i>B</i>-modes for CMBP observations
We analyze the instrumental polarization generated by the antenna system (optics and feed horn) due to the unpolarized sky emission. Our equations show that it is given by the convolution of the unpolarized emission map with a sort of instrumental polarization beam Π defined by the co- and cross-polar patterns …
