Spectrophotometric reflectivity of 11 peculiar objects exhibiting a convex behavior at ~4500 − 6000 Å. Spectra are normalized to 1 at λ = 5454 Å and are consecutively shifted by 0.4 for clarity. This apparent convexity may be created by a concave behavior at ~6000 − 7000 Å, which suggests some absorption feature on their surfaces in this wavelength range. The spectrum resulting from the mean B − V, V − R, and V − I colors, and their standard deviations, for all^∗ objects is shown in gray.
