Abstract
The observed spectrum from a thin accretion disk around a black hole c an be calculated with the help of a transfer function f provided the l ocal emission in the disk plane is given. This function contains the D oppler boost due to the disk rotation, the relativistic light deflecti on, and the gravitational redshift. In this paper the transfer functio n is calculated and some of its properties are discussed. A fast and e asy-to-use computer program is presented to obtain numerical values of f for any set of parameters.
