Fe II emission lines of the symbiotic nova RR Tel

We have used the SAC (self absorption curve) method to analyse the fluxes of optical Fe II emission lines published by Crawford et al. (1999). Certain lines have considerable self absorption. Information about both the populations of the upper and the lower levels of the lines has been obtained. We give limits to the temperature and radius of the line emitting region.
