Estimating phase integrals - A generalization of Russell's lawAn attempt is made to demonstrate, by means of Hapke's (1981) photometric function, that a simple and reliable method exists for the estimation of phase integrals from limited higher phase angle measurements. This method is a generalization of the approximation first proposed by Russell (1916) and more recently treated by Veverka (1971). It is shown that this generalization of Russell's law can employ observations anywhere in the range of phase angles from 40 to 90 deg; optimum estimates of q will be obtained if the data near 70 deg are obtainable.
