Contrast sensitivities as in Fig. 1, but for the range of subsamples described in Sect. 2.2. The target brightness range is in general G = 6 − 12, except for the two samples divided into G = 6 − 9 and G = 9 − 12, as noted in the panels. “Red” and “blue” targets are defined as cooler or hotter than 5000 K, respectively. The ecliptic equator sample is targets within 30° of the ecliptic plane, while the polar sample is the complement. The corresponding dividing angle for the Galactic plane samples is 15°.
