From simulations at a fixed resolution, we show that the variance V( k) is a complex function of the size and volume fraction of the ordered regions present in the amorphous matrix. However, the ratio of the variance peaks as a function of diffraction vector k affords the size of the ordered regions; and the magnitude of the variance affords a quantitative measure of the volume fraction. From comparison of measured characteristic length with model simulations, we are able to estimate the size and volume fraction of ordered regions.
