“…These measurements were made for three different azimuths, q5 = 0", lo', where 0' corresponds to the (1iO) direction. As has been mentioned earlier by several authors [2,5,7], the results of the averaging method are improved by including the whole range and a finer mesh of azimuthal angles. For technical reasons this was not possible during this study but we believe that the error in the layer spacings is essentially due to the limited range in azimuthal angles.…”
