Notes. The last two columns provide the number of sources in each priority class contained in the input mock catalogue and the number of such objects selected (in any one of the three dithers). The galaxy properties (redshifts, magnitudes and line intensities) used to define the priority classes are all derived from the simulated NIRCam photometric information present in the mock input catalogue. In particular the redshifts and the line intensities were obtained by fitting the spectral energy distribution of the objects derived from the mock photometric points. We note that the definition of the priority classes and in particular of the various thresholds that were used depends on the depth of the observations as well as on the scientific goals of the survey. Therefore, they may not be applicable directly to other observations.
