2. Target Count Rates
... We now consider estimation of count rates for objects with stellar, power law, and emission line spectra. To estimate the number of electrons collected from a point source of apparent visual magnitude V, one can use the equation: . ... If one knows the spectral index a (which is zero for a source with a flat continuum), V + AB_nu can also be calculated as the monochromatic Oke system magnitude at the corrected mean wavelength of the filter: . ... 6.3.3 - Count Rates for Emission Line Sources . ...

3. Point-like Sources
... When the source-detection algorithms has run omdetect will compute raw count-rates for each detected source. For point-sources (ie those sources having widths consistent with those of the point-spread function) the count-rates are obtained by aperture photometry. For binned and unbinned images the aperture is 6 and 12 pixels, respectively. ... Extrapolate (if necessary) the source count-rate to the 12 unbinned pixel aperture, using the point-spread function for the filter. ...

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. ...

16. RCJ0311+0507
... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...
