... Welcome to the GIMP Tutorials Pointer Page! This page is to help not only to find a particular tutorial, but also to promote the creation of more tutorials as well as providing an easy index to some examples of what the GIMP can do for you. If you have written up a tutorial, and would like it added, please send a quick piece of e-mail to me , including the URL of the tutorial, and I'll add it. ...

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 ...

Geomagnetic disturbances can be monitored by ground-based magnetic observatories recording the three magnetic field components. The global Kp index is obtained as the mean value of the disturbance levels in the two horizontal field components, observed at 13 selected, subauroral stations . ... Geomagnetic activity is the occurrence of K variations. ... But K still remains a local index, describing disturbances in the vicinity of each observatory. ...

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. ...
