Average optical depths of the line depression formation in the center of the solar disk for eighteen selected Fraunhofer lines have been calculated for six solar atmosphere models given by Vernazza et al. (1981). Some regularities in the behavior of the average optical depths vs. central residual intensities of the line profiles and lower level excitation potential have been examined.
