An extract from the along-scan error correlations averaged over 20 satellite revolutions, against the rotation phase of the satellite. The green line shows the positive error correlations for sources separated by no more than 1 arcmin in transit phase (1 s in transit time). The red and blue lines show the error correlations for sources separated by ±17 arcmin respectively. All of the larger peaks can be related to clanks, and can be observed as such in a reconstruction of the satellite spin rate.
