Scientific paper

An optically thick relativistic Keplerian accretion disk model is used to fit the broad component of the H-alpha, H-beta, and He I 5876 A emission line profiles of the active nucleus of NGC 985. A set of values of the relevant parameters is derived from the independent fits of the three lines. Those values are consistent for the lines examined and consistent with the observations, and are within the ranges expected for accretion disks on the basis of current models.
