Relative strengths of the different SED-matched detection filters with respect to star color. We match our detected sources with the Dark Energy Survey DR1 source database in order to show an accurately measured color for each source. We plot the detection strength (sensitivity) of the “Blue” and “Red” SED-matched filters vs. the “Yellow” filter. That is, a source with relative strength 1.1 in the “Blue” filter would be detected at 5.5σ in the “Blue” filter if it were detected at 5σ in the “Yellow” filter. As expected, sources with blue g − i colors are most sensitively detected by the “Blue” SED-matched filter, sources with intermediate colors are most sensitively detected by the “Yellow” filter, and red sources are most sensitively detected by the “Red” SED-matched filter. The g − i colors to which the detections filters are matched are marked with vertical lines. Note that the relative sensitivities can be tens of percent, which is very significant at low signal-to-noise ratio levels. The filters are roughly equal at the midpoint between the colors for which they are tuned.
