1. Identities
... Some equations, identities or formulas contain small quantities , and these can be made much simpler and easier to use by sacrificing a little accuracy. ... When we derive squares, 3rd powers, 4th powers etc. of numbers larger than 1 , the results are always bigger , while for numbers smaller than 1 , the results are always smaller . ... power . ... number . ... The above also holds for negative numbers, if one understands "bigger" and "smaller" to refer to the absolute value (the value without sign...

3. Fit a source with a small number of net counts
Next: Inspection of results Up: *fit* - Fit Data Previous: Verbose Mode . If the number of net counts for a source is less than it is impractical to fit the data in all 34 energy bits. However, if the flux is required, then a fit must be performed first. ... Fit will then calculate the normalization of the model and xflux can be used to determine the flux and luminosity of the source from the best fit model. xs> fit rebin=yes . ...

6. Number of accreting X-ray binaries of selected types
... The numbers of three types of compact binaries containing accreting NSs and BHs, which are most interesting from the point of view of their observational appearances, have been calculated as a function of time: i) X-ray transient source containing a NS in an eccentric orbit around a main sequence Be-star (the observed prototype: A0535+26), ii) BH The evolution of the selected types of X-ray binaries during the first 10 million years after the starburst onset is presented in Fig. ...

7. Model realization and some results
... The perceptron structure, on the basis of which the database is built, is defined by a number of the input and output parameters and a required accuracy. ... The output perceptron data are the expansion coefficients of the scattering matrix elements in series of the generalized spherical functions. ... As the cluster structure depends on the generation conditions the expansion coefficient
