On the hydrogen spectrum of 3C 273B quasar

The former results on hydrogen line formation in the spectrum of 3C 273 B are revised using new observational data. For explanation of the observed relative intensities and fluxes of hydrogen lines there must exist moderate interstellar or interquasar reddening on the dust. The probability of Lsub(α)-quanta exit must be 10-2-10-3 and slightly diluted ionizing radiation field is probably caused by local sources with the temperature 18000-20000 deg C
