The pointing performance of Planck has been very good throughout operations.
This plot exhibits the pointing errors in Ecliptic longitude for the period Sept. 2011 - Jan. 2012.
This plot exhibits the pointing errors in Ecliptic latitude for the period Sept. 2011 - Jan. 2012.
This plot exhibits a correlation between the periodic component of the pointing error and the duration of the pointing. This suggests a Solar drift origin to this component.
