... epevents (epevents-6.42) [xmmsas_20060628_1801-7.0.0] . ... A pattern analysis is made which yields four distinctive parameters: the number of pixels in the structure, the running pattern number within a frame, the pattern orientation (zero for singles and unresolved patterns; otherwise a three digit code, with the last digit specifying the orientation of the pattern and the first two the position of the pixel on the pattern ) and the distance (in pixels ) to neighbouring ...

... Consequently, it is inappropriate to expand and in ordinary spherical harmonics. The proper expansion expresses both and simultaneously in terms of a particular order of generalized spherical harmonics. ... Generalized spherical harmonics start at , and for each , . ... Generalized spherical harmonics obey a sum rule analogous to a familiar one for ordinary spherical harmonics, but it includes an explicit phase factor which depends on the orientation of the two lines of sight. ...

... This generalization gives rise to the four-dimensional time-frequency-scale-chirprate (TFSC) parameter space. ... We then consider the use of multiple analyzing wavelets/windows, first to generalize Thomson's method of spectral estimation to the TF plane, and then to further generalize this result to the chirplet transform. ... We generalize autocorrelation and cross-correlation by using the signal itself (or another signal) as a ``mother chirplet''. ...

... How to ingest general/static calibration files . How to change names of already ingested calibration files .

... This chapter describes the PEPSYS package for general photometric reductions. The function of photometric reductions is to measure and remove, so far as possible, the instrumental signature from the data. ... The package contains two main parts: a planning program and a reduction program. The planning program interacts with the user to find out the goals of the observing program, and then produces a schedule of the observations needed to meet those goals efficiently. ...

The search for, discovery of, and characterization of planets around other stars has led to a complete revitalization of stellar astrophysics. ... Just as important, those searches for weak signals from the planet-hosting star have produced a rich dataset of observations of the stars themselves. ... The time-series observations from these missions and projects can be examined in many ways to gain insight into stars. ...

... The general scientific activity of the stuff is not a static phenomena, but mainly it lies in the direction, reflected in the famouse book by Ya.B.Zeldovich and I.D.Novikov "Relativistic Astrophysics". ...

... What follows is the list of talks at the IUM general seminar "Globus" delivered during fall semester, 2005. ... In the 1960s, H. Steinhaus asked whether every closed curve in space has a pair of parallel tangent lines; a curve without parallel tangents is called a skew loop. ... A skew brane is a multidimensional analog of a skew loop: it is a codimension 2 submanifold without parallel tangent spaces. ... There exist totally skew n-dimensional spheres in 3n+2-space, and in 3n+1-space if n is odd. ...
