KW - 9969 Braille.The spectral geometric albedo and the bolometric Bond albedo of Triton are calculated using data from the Voyager spacecraft photopolarimeter and science experiments. The geometric albedo is not inconsistent with the presence of a weak absorption feature in Triton's spectrum near 0.75 micron.

It should be noted that in this study, the term geometry refers to arrangement of the surrounding objects in a three-dimensional space at any instant of time. It has been shown that albedo value changes seasonally [9], [10].We predict that the bandpass-integrated TESS geometric albedo is too faint to detect and that a phase curve of HD 209458 b observed by CHEOPS would have a distinct shape associated with Rayleigh ...We then implement our proposed representations with an end-to-end physically-based neural face skin shader, which takes a standard face asset (i.e., geometry, albedo map, and normal map) and an HDRI for illumination as inputs and generates a photo-realistic rendering as output.geometric sequences, given a graph, a description of a relationship, or two input-output pairs (include ... the albedo of this cloud, and how much light is transmitted through the cloud to the ground?

Image tube spectra of the reflectance of the satellite between 3200 and 7400 A are presented which indicate that the surface is composed mainly of rocky (non-icy) material, with violet absorption suggesting a composition similar to that of lunar fines, terrestrial igneous rocks and chondrites.Jan 1, 2004 · A visual geometric albedo of 0.34±0.04 is remarkably high. As virtually no S-type asteroids have geometric albedos greater than 0.30 (Tedesco et al., 1989) , this high value suggests that Braille is a member of one of the rarer classes of stony asteroids: The A-type (olivine rich), the Q-type (olivine and pyroxene-rich), V-type (Vesta-like ... In addition, it should be emphasized that CC21's albedo has yet to be determined.
