Dipole amplitudes and directions for different radiometers. Top: errors in the estimation of the solar dipole direction are represented as ellipses. Bottom: estimates of the amplitude of the solar dipole signal; the errors here are dominated by gain uncertainties. Inset: the linear trend (recalling that the numbering of horns is approximately from left to right in the focal plane with respect to the scan direction), most likely caused by a slight symmetric sidelobe residual, is removed when we pair the 70 GHz horns.
