Figure F32. A–C. Color reflectance measurements, interval 345-U1415I-4R-1, 47–125 cm. Light colors (a* = pink, b* = light blue, L* = gray) indicate measurements made before the drifting behavior of the photospectrometer was fixed (see “Physical properties” in the “Methods” chapter [Gillis et al., 2014e]). Dark colors (a* = red, b* = blue, L* = black) indicate data acquired after the drifting behavior of the photospectrometer was fixed.
