Water map at 66.44 μm observed bythe PACS spectrometer on January 2, 2011. Saturn is represented by the black ellipse and its rotation axis is shown with a black dashed line. Iso-latitudes are plotted with gray lines. The beam is represented by a blue dashed circle. Each black dot represents the central position of a pixel of the raster map. Top: image of the continuum (in Jy), after the residual pointing offset was corrected. Bottom: the line area in microns × % of the continuum is shown.
