For particles of very large sizes, scattering can be considered as a result of interference of the rays having multiple reflections and refractions according to the laws of geometrical optics. ... The papers [ 413 , 414 ] presented a method where the scattering field was expressed via the field at the particle surface using the Huygens-Kirchhoff principle, and reflection and refraction laws were employed to find the unknown field (the approach was called physical optics approximation). ...

In regions of the sky where two or more sources have overlapping point spread functions, it is often difficult to resolve the number of sources and their locations. ... As an example, Nolan et al.(1995) list a source 0445+62 at l = 146.89 , b = 10.65 , with a = 4.0 and a source 0500+59 at l = 150.52 , b = 10.25 , with a = 4.2. ...

... We compare our results with the GRANAT X-ray observations of the Galactic center (Churazov et al. ... It is instructive to compare our results for the Galactic center starburst with what might be expected for a continuous star formation, with the average rate characteristic for the whole Galaxy. For this continuous star formation model, we would expect to observe in the region of around the Galactic center about 10% of the total number of X-ray sources in the Galaxy. ...
