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 -- 2008-07-02 ...

. Last modified: 17 December 1998 . Original version 17 December 1998 . Modified: . The schedule through February 10, 1999 is given on the schedule page. At present there is no long term schedule. We will attempt to make minimal changes in the previous long term schedule through May 1999, but this will depend on the status of HALCA as it begins observations.

... 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. ...
