Next: The Quasi--Newton Method. Up: Outline of the Previous: The Newton--Raphson Method. ... At each iteration, one computes . ... 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. ...

XMM-Newton Science Analysis System . ... CORR_RATE - The count rate after the following corrections have been applied; . 1) A further point-spread function correction may be applied, to extrapolate the counts from 12 to 35 pixels (presently only done for UV observations) 2) Correction for dead-time. 3) Correction for the OM sensitivity-degradation. A key-word TDS_CORR is added to the table to record the correction value. ... XMM-Newton SOC/SSC -- 2006-06-28 ...

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 . ...

... the radiative transfer equation (RTE) for the randomly-irregular magnetized plasma has been derived on the base of general grounds of the multiple scattering theory . ... Solutions of several absolute tasks of the scattering theory have been obtained (on the optical depth of the ionospheric plasma layer, on the value of radio wave anomalous attenuation, on anomalous refraction, on the backscattered signal intensity for the source being placed within a plasma layer). ...

... 18sep08: bias for 3a/3b changed. Look at p2030 data (polA,polB summed) . 21sep08: bias for all beams changed. ... The wapps in 3 level mode take 100 MHz bw with 64usec sampling and 256 lags. alfa is centred at 1440 Mhz with the 100 Mhz 1390-1490 filter int. The total power was computed and then averaged to .1 seconds. ... Beam 6b is dead and p2030 is adding polA + polB. ... The a2010 data taken on 21sep08 was analyzed to check the stability of all the beams after the bias changes in alfa. ...

... The department was founded in late sixties by Prof. D.Ya.Martynov, who for many years was also the director of Sternberg Astronomical Institute. At present time, the head of the department is Prof. A.M.Cherepashchuk, a pupil of D.Ya.Martynov and his successor as the director of SAI. Since Prof. Martynov, the scientific activity of the department was primarily related to binary stars. ... The department consists of 15 members most of which have Ph.D. in Astrophysics. ...
