Abstract: [eng] [cze]
The analysis of the broad iron line profile in the X-ray spectra of active galactic nuclei and black hole X-ray binaries allows us to constrain the spin parameter of the black hole. We compare the constraints on the spin value for two X-ray sources, MCG-6-30-15 and GX 339-4, with a broad iron line using present relativistic line models in XSPEC - LAOR and KYRLINE. Analýza profilu široké čáry železa v rentgenových spektrech aktivních galaxií a mikrokvasarů nám umožňuje určit spin černé díry. Porovnávame výsledky pro dva rentgenové zdroje, MCG-6-30-15 a GX 339-4, se širokou čárou železa pomocí současných modelů relativistické čáry v programu XSPEC - LAOR a KYRLINE.
