(Simplified) ROS executed for each field, observing four dithered pointings. Each pointing results in a I_E, Y_E, J_E, and H_E image and one spectral exposure, RG_E. Filter and grism wheel movements are shown, together with stabilisation times (‘Stab’). Not shown are wheel movements during the dither slew, readout and processing done simultaneously with other operations and slews, overheads, and various inline calibrations.
