... Empirical and theoretical modeling of 3-D structures in the solar corona is confronted by the tremendous amount of data needed to represent phenomena with a large dynamic range both in size and magnitude, and with a rapid temporal evolution. Octree representation of the 3-D coronal electron distribution offers the right compromise between resolution and size, allowing computation of synthetic images of the solar corona. ... The time interval between images is one day. ...

... In the western literature this method is now called ``coupled dipole method" (CDM). ... Thus, a system of equations relative to the fields scattered by the elementary domains can be obtained, and summation of these fields gives the total scattering field. ... A subtle difference between both methods is in the fact that in the first method one works with the fields which excite a dipole (without the field of the dipole), whereas in the second method one uses the real fields in a given domain. ...

... arXiv.org . ... Modeling Light Curves for Improved Classification . ... These include heterogeneity of the data, irregularly sampled data, missing data, censored data, known but variable measurement errors, and most importantly, the need to classify in astronomical objects in real time using these imperfect light curves. We describe a modeling-based approach using Gaussian process regression for generating critical measures representing features for the classification of such lightcurves. ...

... The light baffles consist of the wind baffle that surrounds the telescope and doubles as a light baffle, the primary baffle that extends from the primary center-hole toward the secondary (left), the secondary baffle that extends from the perimeter of the secondary toward the primary (right), and the conical baffle that is suspended approximately halfway between the primary and secondary (middle). The wind baffle is covered with panels that are 25% porous to the wind. ...
