Observation sequence for each pointing. The observing block, composed of a simultaneous VIS and NISP/spectroscopy exposure and three NISP/imaging exposures (Y, J, H), is repeated four times, with small jitters (100′′× 50′′). The blue boxes F and S stand for overheads that are due to the rotation of the filter wheel and shutter opening/closure. Figure adapted from Laureijs et al. (2011).
