Statistical inversion method for binary asteroids orbit determination I.Kovalenko, D. Hestroffer, A. Doressoundiram, N. Emelyanov, R. Stoica ikovalenko@imcce.fr (IMCCE - LESIA, Paris Observatory) Introduction We focus on the study of binary asteroids, which are common in the Solar system from its inner to its outer regions. ... Particularly, we use the Metropolis-Hasting algorithm with Thiele-Innes equation for sampling the orbital elements and system mass through the sampling of observations. ...

... The Science Operation Department is composed of Astronomers, Telescope Instruments Operators(TIOs) and Data Handling Administrators(DHAs). ... Astronomers have proposed several methods to quantitatively measure the amount of turbulence above the telescope, which the most common ones is Differential Image Motion Monitor (DIMM). In optical testing, the Hartmann test is the common method to test the quality of optical components. ... Hartmann mask consists of 48 lenses. ...

... Rocket History . Most people have at least an intuitive notion of the center of gravity (CG) of an object: it is the point on which the object can be perfectly balanced. Grab a broom at one end and the other end tries to drop down; grab it at its center of gravity, and it stays balanced, neither end tipping over. ... Suppose we have a rocket of total mass 2M , of which M is payload and M is fuel. ... Total mass . ... Each time the velocity increases by one notch, the mass doubles . ...

L. E. Dreyer (1888, 1895, 1908). ... The order of the new catalog is strictly by right ascension, the NGC and IC objects being merged into one machine-readable file. ... The book also contains a table of right ascensions for NGC and IC objects. ...

... The NOTE element is designed for use as admonishments such as notes, cautions or warnings, as commonly used in technical documentation. The CLASS attribute specifies the type of the element and is typically associated with different graphics such as a road traffic warning sign. ... The class names: NOTE, CAUTION and WARNING are recommended for standard admonishments. In the absence of the CLASS attribute, a NOTE element is typically rendered indented, without an accompanying graphic. ...
