Table A.1.
Mean (ν) and standard deviation (σ) on sample and line residuals from the calculated body centre in pixels for each satellite (Cassini-ISS data). N is the number of observations by satellite considered and for each coordinate. Observations with residuals higher than 2.5 pixels were discarded. NAC stands for the Narrow Angle Camera of the Cassini Imaging Science Subsystem.
