... Under the data of the catalogue of HI absorption line obtained on RATAN-600 it is revealed 98 interstellar HI clouds with the sizes from 0.2 up to 20 pc, with masses from 10E-2 up to 100 masses of the Sun also spectra of the sizes, concentration and masses were constructed. ... The comparison of an obtained spectrum of masses with theoretical ones has shown, that at large masses in interstellar matter the process of coalescence in cloud-cloud collisins predominates. ... Figure 1. ...
Broadband SED of Ser X-1 constructed with simultaneous data and upper limits from ISGRI (filled diamonds), PICsIT (filled pentagon), JEM-X (filled squares) and ASM data (open square) plus non-simultaneous optical measurements (filled dots), NIR and far-infrared upper limits (open circles and open triangles, respectively) and radio data (filled triangles). Error bars of data points are not reported as their size is comparable to, or smaller than, that of the symbols used in the figure. ...
Authors: Yu.G. Shevelev , V.A. Marsakov , . ... We have constructed and investigated properties of metallicity function of disk stars with different ages, proceeding from the statistically restored real altitude distributions of stars at the solar galactocentric distance. It is shown that the metallicity distribution of stars in each age range is not of Gaussian form, but it may be considered as a superposition of two normal distributions centered at -0.2 and 0.0 dex. ...
. A distribution list is very useful where a group of users need to communicate amongst themselves on a regular basis. Each list is given a name just like any other user. By addressing a message to the list name, the sender can be sure that everyone will receive a copy. You cannot set up a distribution list yourself. Ask your system administrator to set one up for you.
... One of the most widely used tools of Fourier analysis is the Parseval theorem. It enables the experimentalist to view how the `energy' in the signal is distributed among frequencies. The Fast Fourier Transform (FFT) algorithms have made power spectra one of the obvious diagnostics tools during data acquisition, and energy maps are a versatile alternative. ... The result is an energy map (Fig. 9), showing the distribution of energy corresponding to the wavelet map (Fig. ...
USING THE CORRELATION BETWEEN ISGRI SURVEY RESULTS AND OTHER CATALOGUES TO AID SOURCE IDENTIFICATION John B. Stephen, A. Malizia and L. Bassani IASF-INAF, Via P. Gobetti 101, 40129 Bologna, ITALY, E-mail: stephen@iasfbo.inaf.it ABSTRACT In order to help in the identification of INTEGRAL/ISGRI sources, we have developed a software package which allows a rapid and detailed cross-correlation to be performed between various source catalogues. ... We show below some preliminary results from this analysis. ...
