The descriptions below focus on the meaning of each filename parameter, leaving the exact details of the inferred default value to be explained in the algorithm section. evlist . ... file . The response matrix file (OGIP-compliant format). ... If a spectrum file is not provided ( withspectrum =no) this parameter specifies the INDEX number of a source in the source description list (parameter srclist ), and thereby the incidence angle and selection regions for the response matrix. ...

... We demonstrate through numerical simulations that model parameters estimated with our technique are essentially bias-free, even when the average number of counts per bin is 1. ... The IW technique avoids such biases by estimating through successive iterations, where for each iteration, j, , and the best-fit parameters are determined by minimization of . ... In our sample, we find that the minimum values and best-fit parameters converge after about 6 iterations. ...

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. ...

The most recent kpyymm.tab (yymm stands for year and month, each expressed with two digits) files are distributed per e-mail half-monthly by Dr. H.-J. Linthe, mailto:kp_index@gfz-potsdam.de Both recent and past tables are supplied as an archive on the FTP servers . ... Since many observatories are interested mainly in the international quietest and most disturbed days, beginning August 1996 three extra lines have been added to the end of the table containing these values in an easy to read form. ...
