Our notes briefly list the optical characteristics that are necessary for radiative transfer (RT) calculations. For further reading we give a list of works developing the RT codes for astronomical applications. ... A part of these notes (the section on the radiative transfer approaches) was addded by V.Il'in S.Grachev. The page of Jurgen Steinacker provides access to several radiative transfer codes, some useful tools, and benchmark results. ...
