... imweightadd (tools-1.63) [xmmsas_20070708_1801-7.1.0] . ... In order to estimate the optimal weights, imweightadd needs two lists: a list of background maps and a list of source relative expectation values . The first job is to reduce each background map to a single representative value of background counts per pixel. ... Source detection is likely to be most sensitive near the centre of the image; this is also the place where one would expect the maximum to be in the background values. ...

In the light curve depicting their observations, definite trends are noted, here is a "thumb-nail" analysis of the the magnitude estimations of the bright SN (1989B) in the galaxy NGC 3627 (M66). ... The observations were inserted against the V magnitude templete of BL, CCD photometric data, (Wells et. al, (1994) and a color trend (B-V) histogram of the mean type Ia SN (BL)(nutemp.gif).

... Microlocal Analysis is a theory of Pseudo-Differential Operators and Fourier Integral Operators (PDOs and FIOs). ... Microlocal analysis comes in few flavors. ... We will consider semi-classical PDOs and FIOs: one can always get from there to standard PDOs and FIOs but semi-classical theory has more applications. Less formal description of (semi-classical) microlocal analysis is ``a semi-classical limit of quantum mechanics'' or ``high-frequency limit of electrodynamics'' (etc). ...

... 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. ...
