Top panel: shows the variation of the pointing of the HGA (boresight and -3dB values) on the solar disk which is represented by a +/- 0.42° band.

Middle panel: the same information as in panel 1, presented in a different way. The projection of the solar disk on the HGA beam is pictured every 10-15 minutes during the checkout. An artificial vertical displacement of + or - 5° has been applied on every other plots to enhance the clarity of the figure.

Bottom panel: the time variation of the AGC value for both chains is plotted. The AGC varies between -102 and -108 dB. The AGC variation is clearly correlated with the HGA pointing variations.
