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 . ...

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. ...

... 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. ...
