Line width variations combined with simultaneous electron density estimates, provides a very powerful diagnostic for the solar corona. ... They find that for distances of a few arc seconds outside the solar limb, the average line of sight electron densities in the coronal holes are about a factor of 2 lower than in quiet sun regions. ... The Western limb data showed a similar trend. ...

... The Arecibo 430 MHz radar uses incoherent scatter to determine the characteristics of the ionosphere. It is part of a chain of incoherent scatter radars operated by the Upper Atmospheric Facilities program of the National Science Foundation with strong links to the CEDAR program and the National Space Weather program. ... The Arecibo radar is extremely powerful and sensitive; it is capable of making very accurate measurements of many ionospheric parameters. ...

Next: CONSTRICTOR parameters for astrometric Up: Astrometry data reduction Previous: Astrometry data reduction Contents . Astrometry with NPOI is based on the measurement of fringe delays, which are related to the baseline orientation and star position. There are three different corrections to the uncalibrated FDL delays, which are due to atmospheric refractive index fluctuations, path length variations in the feed system, and motions of the siderostat pivots. ...

... Archives . ... People . ... At least two images for reconstructing a 3D scene is a conventional belief. ... Luckily you can test such progress, reconstructing a 3D scene from a single still image at Make3D (a click brings you to Make3D at Stanford). Among thousands of pictures, there are only a few astronomical pictures, a few galaxies and a nebula and reconstructing 3D astronomical scenes from these small number of single still images is disappointing to me compared to other types of images. ...

... The performance of a detector can be characterized by its efficiency for measuring individual x-rays or for measuring Bragg peak intensities. The performance for detecting individual x-rays is well modeled by the DQE. The performance for measuring Bragg peak intensities in the presence of an x-ray background can be modeled by an expanded definition of the DQE which allows inclusion of experimental constraints, the XDCE. ... The x-ray background per pixel has decreased. ...

... The most powerful and widely used methods to calculate the scattering matrix of a fractal cluster are based on the coupled dipoles methods (e.g. the Discrete Dipole Approximation, DDA) and the theory of light scattering by a cluster of spherical particles [2-4]. ... At present the procedure of calculation of the scattering matrix is well developed for both an oriented cluster of spherical particles and for chaotically oriented clusters of such particles [4]. ...

... A timeseries is created by evselect from an event list which includes events from the exposure/instrument/ccds of interest. ... The events that end up in the time series represent only a fraction of the photons from that source which impinge on the aperture of the mirror. ... Events outside of good time intervals (GTIs); . ... Some things that belong to the `involuntary inefficiencies' list also behave like selections (eg the lack of events on a bad pixel), because of their all-or-nothing character....
