... flspec computes the spectrum of the background fluctuations in EPIC Imaging data. ... Once the 'flatfielded' image is free from detected sources, its pixels are binned according to the input parameter binsize and classified as 'positive' (if they have more counts than the median in the image) and 'negative' pixels (less counts than the median). ... Once created, positive and negative spectra are subtracted to obtain the 'fluctuations' spectrum in each annular region. ...

... A technique allowing automatic representation by a relatively small number of independent parameters based on the principal component analysis of data sequences is presented. ... In recent years the spectrum of observed astronomical data can be characterized as greatly varied. ... In this instance, the problem of initial description and classification of newly-observed data becomes most urgent, especially if there is a lack of preliminary observational material and theoretical expectations. ...

. The polar diagram shows the spacecraft corrected geomagnetic co-ordinates : co-latitude - local time . The geomagnetic co-latitude in the range (10 ° , 50 ° ) is shown with 10 ° step. The geomagnetic local time meridians correspond to 6, 12 and 18 hours. The different colours are used for each of the 4 spacecraft. On the plot the SC names are shown by the corresponding colours.

... 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). ...
