Notes. In each case the window class (WC) is given followed by the number of samples in the AL and AC directions, the number of pixels in the AL and AC directions that have been binned to produce each sample (in brackets), and whether the resulting observation corresponds to the LSF or PSF. The solid black lines indicate the geometry of each sample and their arrangement to form the window; thefaint dashed lines indicate the pixels that have been binned to produce each sample. A combination of on-chip and numerical (software) binning is applied to optimise onboard performance and telemetry budget.
