Illustrating the principles of Gaia windowed readout: images and spectra are measured via windowed sampling with unwanted pixels in between windows being flushed at high speed. The timing of window samples changes with respect to readout freezes (associated with parallel clock pulses), and braking samples are inserted after flush sequences where time allows.
