Albedo used in astronomy are the (V-band) geometric albedo (measuring brightness when illumination comes from directly behind the observer) and the Bond albedo (measuring total proportion of electromagnetic energy reflected). Their values can differ significantly, which is a common source of confusion. In detailed studies, the directional reflectance properties of astronomical bodies are often expressed in terms of the five Hapke parameters which semi-empirically describe the variation of albedo with phase angle, including a characterization of the opposition effect of regolith surfaces. The correlation between astronomical (geometric) albedo, absolute magnitude and diameter is: formula_7, where formula_8 is the astronomical albedo, formula_9
Albedo (role-playing game) Albedo (role-playing game) Albedo is a role-playing game based on Steve Gallacci's and "Birthright" storylines from the comic anthologies "Albedo Anthropomorphics" and "Critters". "Albedo: Platinum Catalyst" is characterized by the notable player-controlled troupe of characters, the main character and four supporting retinue. The main character is more fleshed out than his supporting characters which typically have 3 stats (species, morale, job description) and a weapon. Morale is a character's ability to keep cool; when a character is shot or witnesses an explosion, they lose one point of this stat. Green soldiers will typically start with one morale point if they
