is simulated with a very bright magnitude, but at a wavelength far from the peak transmission of any of the filters, will be detected with a somewhat dimmer magnitude at a wavelength corresponding to the image in which it is brightest. Fig. \[fig:simresults\] shows both the simulated (on the left) and detected (on the right) quantities for each of the three fields.
