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. ...

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. ...

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. ...
