Values of the photometric perturbations required in the frequency-domain analysis for the accurate determination of parameters characterizing stars in eclipsing binary systems when some degree of 'proximity effect' complications are present in the light curves are tabulated, corresponding to a wide range of such parameters. The relative smallness of the perturbation values permit a rapidly convergent iterative approach to the final parameter specification. Also, in view of the relative smallness, linear interpolation from the table over a wider range of nontabulated parameters should be effective in assessing the effects of the perturbations in a general case. An illustrative application to the light curve of RT Per appears to confirm this.
