    • The axial tilts of Jupiter and Saturn are 3.13° and 26.73°, respectively. Saturn's orbital period (and seasonal cycle) is 29.4 years.

    • note
    • A global map of Saturn, obtained by imaging Saturn's disk every 60° longitude as the planet rotated below the spacecraft, was acquired roughly every other rotation of Saturn. The spatial resolution of the narrow-angle camera ranged from 425 to 156 km per pixel. Images were navigated on the planetary limb, calibrated radiometrically, assembled into spatial mosaics, and mapped with a simple cylindrical projection. Illumination effects were removed by dividing the brightness value by the cosine of the solar incidence angle. Images from 29-30 May were part of a campaign to view Saturn at near-IR wavelengths.

    • The solar phase angle was ∼65°. The subsolar and subspacecraft planetocentric latitudes were -25° and -16°, respectively.

    • -1. Limited illumination and contrast within Saturn's cloud bands made identifying features more challenging than at Jupiter. Two authors (A.R.V., J.B.) tracked features with the use of different methods. One selected the initial and final tie points by eye. The other selected the feature by eye but used a digital correlation window to objectively determine the tie points.
