... There are many pitfalls in these kind of comparisons, which are described in great detail in the papers I have used to compare my impact on the field. In the first comparison I use the method described by Pijpers (2006, Astronomy Geophysics, 47, 6.17) , where he compares the total normalized citation rate per paper (i.e., the number of citations of a paper divided by the number of authors) to the total number of papers for different authors in the field of space research. ... 1st year paper . ...

... We have assumed a constant in time star formation rate and the total number of stars in the Galaxy, , to be such that the total mass of the galaxy is ; assuming the Salpeter mass function   , we get . ... This number agrees with a standard estimation of the galactic star formation rate of order of per year. In each run of calculations, we trace the evolution of binaries with initial parameters randomly distributed according to the chosen initial laws. ...

Next: Feature enhancement: local Up: No Title Previous: Feature enhancement: filtering . ... As a result, a common magnitude scale (contour lines on the maps above, or color scale on Fig.1) will poorly display the short-duration events in a signal. Normalizing each line of the map (fixed duration) so it has unit variance (in effect dividing the energy map by the mean energy spectrum) at each duration restores more details of small-scale activity (Fig. ...

... A frequently used procedure, alternative to the correction for the chromatic response, is to normalise the continuum to unity by dividing the observed spectrum by a smooth approximation of its continuum. This approximation can be obtained either interactively with the graphic cursor, or from a table (command NORMALIZE/SPECTRUM ) or by dividing the raw data by itself after filtering or smoothing. Median filtering and running average algorithms are well suited for this purpose (command FILTER ). ...

... It was shown in the early 1980's that spectral lines formed around 1-2.5 x 10 5 K were enhanced in radiance by factors up to 15-25 over the normal quiet Sun. From the dynamical viewpoint, this would suggest a pressure imbalance between the sunspot and the surrounding region. ... Here, the electron density was evaluated over a bright sunspot plume region using lines within the O V 760? multiplet. ... The derived densities in all four regions are indicated. ...
