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 . ...

Next: The Model Up: No Title Previous: Radiopulsars as Sources of . In this section, we study the evolution of stellar populations on a time-scale of 10 Myr for a starburst љ occurring under conditions similar to those in the Galactic Center (see Lipunov et al. (1995d)[ 126 ]). We estimate the expected number of X-ray transient љ sources (NS + MS star), super accreting BH, and BH + supergiant binaries, all as functions of time elapsed after the burst. ...
