For example, modified Newtonian dynamics (MOND) has no relativistic extension, and so makes no firm lensing predictions, but galaxy-galaxy lensing data can be used to empirically constrain the deflection law of a MONDian point-mass. ...

The Astronomical Society of Australia has been asked by STANDARDS AUSTRALIA to compile a list of "designated" optical observatories that are valuable resources for (i) research, (ii) education and (iii) community use. The ASA is the final arbiter of whether any particular observatory is so designated. ... Upon receipt of your application form, your observatory will be entered on a list of "Pending Designated Observatories" on the ASA Home Page. ... It will be emailed for you. ... Email . ...

On January 23, 1998 the space probe NEAR was on its way to its closest approach to Earth. Shortly before this, a so-called sunglint event was scheduled: by re-orienting its solar panels in order to reflect sunlight onto Earth's surface, the probe would shine for a few minutes brighter than any star in the sky. ... However, we were able to record a series of images of the space probe shortly before the sunglint event, and we have assembled them into a movie. ...

... His early works dealt with statistical methods especially in atmospheric, geomagnetic and ionospheric tides. In 1928, Bartels became professor in Eberswalde; in 1936, he became director of the Potsdam Geophysical Institute and full professor at Berlin university. ... With these statistical methods, he was able to disprove many widely accepted geophysical models on the one hand and develop some very useful and easy to apply geophysical indices on the other. ...

Neglecting the second derivatives matrix , we obtain the ``normal equations'' and the Gauss--Newton direction . This so--called Gauss--Newton method is intended for problems where is small. ... The algorithm implemented here is a modification of that Gauss--Newton method, that allows convergence even for rank deficient Jacobians or for large residuals. ...

GrIm II . ... The MC has been modified to change the way GRIM images are stored to disk when FITS format is selected. ... The solution the Grim team has come up with is to internally add a constant of 10000 to every pixel of the 'bias subtracted' grim image which makes it conform to the unsigned 16-bit number standard, in that all pixel values after this addition of 10000 are in the range 0-65535. ... We have now implemented this for storage of GRIM files in FITS format. ... filetype fits . ...
