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 -- 2007-07-09 ...
