One of the four MSA quadrants (Q3), showing allocation of micro-shutters to targets. The other quadrants are shown in Appendix D. Those shutters in green are covered by both the grating configurations and the low-dispersion prism. The red shutters are open only in the prism observations, as they would lead to overlapping spectra for our high priority targets in the grating configuration. Three micro-shutters are opened for each target, but the nodding by ±1 shutter means that spectra are obtained over the areas covered by five shutters (including background) which are displayed. The field displayed is the NIRCam F200W image, and is 1.8 arcmin on a side. North is up and East is to the left. Shutters with the prefix ‘B’ are empty sky background.
