Next: Parameter estimation Up: Basic principles of Previous: Time domain analysis . A simple way to graphically present the results of a TSA is to plot the test statistics S against its parameter or l , depending on whether the analysis was performed in the frequency or time domain. ... Examples of statistics used in the time domain are covariance and correlation functions. The correlation of a signal with itself or with another signal produces maxima in these functions at particular lags. ...

... Figure 3: Organisation of the EPIC-MOS chain: Bad pixels search. ... In most cases relying on the bad pixels registered in the CCF is not enough. ... Then one of two bad pixel finding algorithms is called (Fig 3 ), depending on badpixfindalgo . ... For badpixfindalgo =EM (or not set), the algorithm is called a third time (incrementally) on energies below 500 eV (and after flare screening), unless lowenerbadpix =N. This sometimes detects bad pixels more easily, because most appear at low energy. ...

... The fitting package in STSDAS (Space Telescope Science Data Analysis System) relies on two basic techniques (one linear and one non-linear) for fitting functions to data. ... Results show that both methods may generate biased coefficients (at the ~few percent level), and over or under-estimate error bars (at the ~10 percent level), in particular from low signal-to-noise data. ... Function coefficient errors are computed directly from the covariance matrix. ... Abscissa is signal-to-noise. ...

... Several attempts to discover the FICN signal in VLBI nutation series made during last years failed. ... We investigated several VLBI CPO series by means of spectral and wavelet analysis. It has been shown that there are several periodic signals with close amplitude around the expected FICN period without any prevailing one that can be reliably associated with the FICN. ... DATA ANALYSIS We analyzed several CPO series obtained in IVS analysis centers by means of spectral and wavelet analysis. ...

... The concepts of Fourier frequency and wavelet duration are obviously related. ... Among many sensible definitions, we chose to require that the peak of the wavelet mean spectrum should be matched with the singularity of the Fourier transform of the cosine wave. Then, it can be shown that the frequency of the cosine is related to the wavelet duration by the relation . ... The ambiguous definition of the duration of an event is common to the sizing of any object of irregular shape. ...

... From our analyses of the extant data, we report that we can find very little in the way of definitive or conclusive evidence for the fracture occurring during the darkrun. We find that there may be a suggestion that the secondary may have been stressed during the darkrun from the analysis of the focus sweep data, but it is, sadly, not the conclusive evidence that was wanted. ... If the fracture happened during the dark run, the figure of the secondary did not change appreciably. ...

This source is hiding behind our Galaxy at a distance of ~18 Mpc, located at a galactic latitide of 0 degrees. ... As we look towards longer wavelengths, 60 micron, to try and penetrate the Galactic Plane, we still see confusion from galactic sources. ... If the image seems some what confusing that is because the MOST is a continuum radio telescope and when it looks in the direction of our Galaxy it detects radiation from sources within our Galaxy and from sources that may lie behind our Galaxy. ...

... As the SN activity in the first generation stellar population must be small at present, the net SN rate in the vicinity of the Sun is approximately proportional to the local density of stars of second generation (or to the star formation rate, which is the same), especially for SN II and SN Ib. If a -like star formation of the first generation stars took place, a hump on the observed - showing the relative fraction of the first generation stars should be observed. ...
